fix: useEffect anti-patterns, attendance permissions, and received-invoices schema mismatch

- Remove ref-mirror useEffect in AuthContext (cachedUserRef already written at mutation sites)
- Replace useEffect slide direction in ReceivedInvoices with render-time computation
- Fix Login.tsx useEffect dependency array (mount-only alert should have [] deps)
- Move "project created" alert to navigation source in ProjectCreate, remove useEffect in ProjectDetail
- Move companySettings defaults into fetch callbacks in InvoiceDetail and OfferDetail
- Replace due_date useEffect with useMemo in InvoiceDetail
- Capture initial snapshots from API data instead of useEffect in InvoiceDetail, OfferDetail, OrderDetail
- Replace localStorage draft useEffect with lazy useState initializer in OfferDetail
- Fix attendance dropdown to filter by attendance.record permission only
- Fix clock-out 404 on update-address (remove departure_time filter for departure action)
- Fix received-invoices stats endpoint referencing non-existent is_deleted and amount_czk columns

+
+## Architecture & Key Patterns
+
+### Request Flow
+
+```
+Request → CORS → Cookie → Rate-limit → Security headers
+       → requirePermission() or requireAuth()
+       → Zod schema validation (parseBody helper)
+       → Route handler
+       → Service function
+       → Prisma
+       → success(reply, data) or error(reply, message, status)
+```
+
+### Response Format
+
+All responses use this shape:
+
+```typescript
+// Success
+{ success: true, data: T, message?: string, pagination?: {...} }
+
+// Error
+{ success: false, error: string }
+```
+
+Use the `success()` and `error()` helpers in routes — never write raw `reply.send()`.
+
+### Service Pattern
+
+Services are plain exported async functions, no classes:
+
+```typescript
+// src/services/foo.service.ts
+export async function getFoo(id: number) {
+  const result = await prisma.foo.findUnique({ where: { id } });
+  if (!result) return { error: "Not found", status: 404 };
+  return { data: result };
+}
+
+// src/routes/admin/foo.ts
+const result = await getFoo(id);
+if ("error" in result) return error(reply, result.error, result.status ?? 400);
+return success(reply, result.data);
+```
+
+### Error Handling
+
+- Routes map service errors to HTTP responses using the pattern above.
+- Global error handler in `server.ts` catches all unhandled exceptions; returns 500 with Czech message.
+- **Never silently swallow errors.** Even if a failure is non-fatal, log it: `app.log.error(e, 'context')`.
+- Error messages are in Czech (this is intentional — user-facing messages, Czech company).
+
+### Permissions
+
+```typescript
+// Route-level guard
+fastify.addHook("preHandler", requirePermission("invoices.view"));
+// or multiple
+fastify.addHook(
+  "preHandler",
+  requirePermission("invoices.view", "invoices.edit"),
+);
+
+// Admin role bypasses all permission checks
+// Permissions follow the pattern: "entity.action" (e.g., "users.create", "invoices.delete")
+```
+
+### Audit Logging
+
+Call `logAudit()` from `src/utils/audit.ts` whenever data is created/updated/deleted.
+Pass `oldData` and `newData` so the diff is stored. Audit failures are non-fatal.
+
+### Validation
+
+Use Zod schemas from `src/schemas/`. All route bodies must be validated:
+
+```typescript
+const body = parseBody(FooSchema, request.body);
+if ("error" in body) return error(reply, body.error, 400);
+```
+
+---
+
+## Date & Timezone Handling (Critical Gotcha)
+
+`src/config/env.ts` sets `process.env.TZ = 'Europe/Prague'` and overrides
+`Date.prototype.toJSON()` to return local time (not UTC). This means:
+
+- `JSON.stringify(new Date())` returns local Czech time, not UTC.
+- All API responses with Date fields will contain local time strings.
+- Prisma stores dates as UTC internally, but they read back as local due to the TZ setting.
+- **Never assume UTC** when working with Date objects in this codebase.
+- When writing new date comparisons or DB queries, use `new Date()` (already local) — do not manually offset.
+- The override exists for PHP migration compatibility and Czech date display.
+
+---
+
+## TOTP / 2FA
+
+- Secret stored AES-256-GCM encrypted in `users.totp_secret`.
+- Supports two encoding formats: PHP legacy (base64 iv+cipher+tag) and TS (hex).
+- Backup codes stored as encrypted JSON array in `users.totp_backup_codes`.
+- When `company_settings.require_2fa = true`, all users must enroll before accessing the app.
+- Login flow: password → if 2FA enabled → issue `loginToken` (5 min, single-use) → TOTP verify → issue access + refresh tokens.
+
+---
+
+## Testing
+
+Tests live in `src/__tests__/`. They use Vitest + Supertest against a real test database (`.env.test`).
+
+- Test coverage is minimal: only `auth` and `numbering` are tested.
+- Use `buildApp()` helper to spin up the Fastify instance for tests.
+- Tests use `vitest.config.ts` with `environment: 'node'` and 15s timeout.
+- **Do not mock Prisma** — tests hit a real database to catch schema/query bugs.
+
+When adding new features, add tests in `src/__tests__/`. Name test files `<feature>.test.ts`.
+
+---
+
+## Frontend Conventions
+
+- Pages are lazy-loaded via `React.lazy()` in `AdminApp.tsx`.
+- Auth state lives in `AuthContext`; use `useAuth()` hook to access it.
+- Alerts/toasts use `AlertContext`; use `useAlert()` to show them.
+- API calls go through `src/admin/utils/api.ts` which handles token refresh automatically (deduplicates concurrent refresh calls).
+- Custom hooks: `useApiCall`, `useListData`, `useTableSort`, `useDebounce`, `useModalLock`.
+- Styling: CSS files in `src/admin/` — no CSS-in-JS, no Tailwind. Use CSS variables.
+
+---
+
+## Database Conventions
+
+- All models use `snake_case` column names; Prisma maps to camelCase in TypeScript.
+- Soft-delete via `is_deleted` boolean (not all tables, check schema).
+- Timestamps: `created_at`, `updated_at` (auto-managed by Prisma).
+- Number sequences (`number_sequences` table) manage invoice/quotation numbering — never hardcode numbering logic.
+- All significant tables have audit log entries. Check `audit_logs` model for the schema.
+
+---
+
+## Known Issues & Gotchas
+
+1. **Date.prototype.toJSON override** — global monkey-patch in `src/config/env.ts`. Side-effects on third-party libraries that serialize dates. Do not remove without migrating all date serialization.
+
+2. **CJS/ESM mismatch in tests** — Server compiles to CommonJS (`tsconfig.server.json`), but Vitest runs in ESM by default. The `vitest.config.ts` resolves this, but be careful when adding dependencies that only support ESM.
+
+3. **Mixed error patterns** — Some services return `{ error, status }`, others return discriminated unions `{ type: 'success' | 'error' }`. Prefer `{ error, status }` for consistency with existing routes.
+
+4. **Silent error catches** — A few service functions swallow errors in catch blocks. Always log at minimum; never use empty catch blocks.
+
+5. **HTML sanitization gap** — Rich text fields in invoices use DOMPurify, but quotation scope and order scope fields may not. If modifying those, add sanitization.
+
+6. **Puppeteer PDF generation** — Runs a headless browser. Input to the HTML template must be sanitized. Do not pass unsanitized user data into PDF templates.
+
+7. **NAS_PATH file access** — Project file uploads write to a network share path. In dev, this path may not be mounted. Features using `NAS_PATH` will fail gracefully (or not) if the path is unavailable.
+
+8. **Prisma client regeneration** — After any schema change, run `npx prisma generate`. The generated client is not committed to git.
+
+9. **No CSRF tokens** — CSRF protection relies on `SameSite=Strict` cookies + CORS. Do not weaken CORS configuration.
+
+10. **Czech locale hardcoded** — Error messages, month names, and some business logic strings are Czech. This is intentional.
+
+---
+
+## Release Process
+
+1. Bump version in `package.json`
+2. `npm run build`
+3. Commit and tag (`git tag -a vX.Y.Z`)
+4. Push to Gitea (`git push origin master && git push origin vX.Y.Z`)
+5. Create tarball: `tar -czf app-ts-X.Y.Z.tar.gz dist dist-client prisma package.json package-lock.json scripts`
+6. Deploy via SSH to production server (`boha_admin@192.168.50.100`):
+   - Path: `/var/www/app-ts`
+   - Backup: `node_modules`, `.env`, `ecosystem.config.js`
+   - Clean directory (keep backups only)
+   - Extract tarball
+   - Restore backups
+   - Restart: `pm2 reload ecosystem.config.js`
+
+Do not push directly to production or restart services without confirmation.
