refactor(ui): migrate remaining inline pages to the concept design language (#1470)

* refactor(ui): migrate remaining inline pages to the concept design language

Catch-up pass for surfaces the 2026-07 UI migration missed:

- Bankavstämning: de-boxed toolbar, dry-table sections (preview, omatchade
  verifikationer, ignorerade, matchade), instructional copy moved behind the
  page "?" (HelpPopover via FocusedReport, sv+en), AttnLine for the dirty-
  dates hint, EmptyState for the blank page, space-y-8 rhythm.
- Report detail views (trial balance, income statement, balance sheet,
  resultat-/balansrapport, reskontror, huvudbok, grundbok, dimension-P&L):
  shared Skeleton/Error/EmptyState shells, border-2 totals bands flattened
  to hairline cards with font-display tabular-nums headline numbers,
  ReportSectionTable rebuilt on the group-band idiom, font-mono money ->
  tabular-nums, house tablist for Förenklad/Detaljerad, GL filter de-boxed
  onto Input primitives, verdicts follow chips-mark-exceptions.
- Extensions browse: PageHeader, locked section headers, rounded-lg
  secondary icon tiles, flat hover shift on cards, p-6 content.
- Återkommande fakturor: page-level list moved off ui/table onto dry-table
  with hover-revealed quiet row actions; Skeleton loading.
- Help: EmptyState for no search hits, flat hover shift on resource links.
- Chart of accounts: spinner loading blocks -> Skeleton rows.
- Kunskap graph + salary calendar popovers: rounded-lg, Input/Textarea
  primitives instead of hand-rolled shadow-sm controls.

No logic, endpoint, or data changes. Verified via sandbox screenshots;
lint 0 errors, 13214 tests green.
