Server-side, per-user chat history (the thread now survives reload): - new ai_chat_messages table + migration; getChatHistory/appendChatMessages/ clearChatHistory; GET/POST/DELETE /api/admin/ai/history (ai.use-guarded); service + HTTP tests (isolation, ordering, clear, perm, validation). - DashAssistant loads the thread on mount and persists each turn; "Vymazat" clears it. gcTime:0 so each mount re-reads the DB (no stale-cache resurrection); composer gated until history settles + seed flag flipped on submit (no seed/submit race clobbering a freshly-sent turn). UX + correctness fixes from review/feedback: - review cards moved OUT of the scrollable thread into a "Faktury k potvrzení" section so Uložit is always reachable; chat auto-scroll no longer fires on field edits. - chat bubble text colour set on the Typography (GlobalStyles pins `p` to text.secondary, which was overriding the inherited bubble colour → unreadable). - never clear input/staged PDFs on a failed submit (rollback + keep), so a budget error can't wipe staged invoices; roll back the optimistic user turn. - stable attachment ids (no crypto.randomUUID — undefined over plain HTTP). - editable Datum splatnosti + Popis fields; client-side extraction summary. Security: DashProfile clipboard copy now uses an execCommand fallback (works over plain HTTP) and only shows the success toast when the copy actually succeeded — previously it falsely claimed to copy 2FA codes / the TOTP secret.
