fix(uat): prod UAT batch — reports, sidebar, search, berths, breakpoint

- financial report: drop Expenses KPI, Net Contribution, cash-flow chart,
  expense donut + ledger (expenses are business-trip costs, not net contribution)
- dashboard report PDF: pagination-safe tables (TableSection + per-row wrap)
  so long doc lists no longer overlap/crush
- clients PDF report: rename "Nationality" -> "Country"
- sidebar: hide a section header when all its items gate off (FINANCIAL orphan)
- topbar: move global search into the 1fr grid track so it can't overlap "New"
- clients card: show all linked berths (not just latest interest's primary)
- berths list: hide table-only toggles (ft/m, density, columns) in card mode
- lists: lower table/card breakpoint lg -> md so narrow desktops get tables
- alert-rules: stale floor created_at -> updated_at (survives created_at backfill)
