fix(freshness): converge invalidation sets; global query-error toast; silent-toggle feedback

- OrderDetail/InvoiceDetail/LeaveRequests mutations now invalidate the same
  domain sets as their list-page twins (orders+offers+projects+invoices /
  +projects / +users+dashboard) — no more stale project/order labels after
  a detail-page action.
- USER_INVALIDATE hoisted to lib/queries/users.ts; DashProfile self-edit now
  refreshes trips/attendance/leave/projects like an admin edit.
- Global QueryCache.onError toast: failed first-loads no longer masquerade as
  empty lists (data-present refetches stay silent; Unauthorized skipped; 4s
  rate limit; meta.suppressGlobalErrorToast opt-out used by offer/issued-order
  detail + the local TOTP QR query).
- Users/Vehicles active-toggle mutations toast on error (was silent revert);
  clickable status chips got affordance tooltips (incl. warehouse parity).
- AuditLog: refetchOnMount always + staleTime 0 (mutations write audit rows
  but nothing invalidates the key); search debounced; dead auditLogOptions
  module removed.
