feat: propagate right-click "add as keyword" to transactions page and highlights list (#75)

Wire the ContextMenu + AddKeywordDialog pair onto the remaining per-transaction
surfaces. No new business logic — pure composition of #69 / #74 pieces.

- HighlightsTopTransactionsList: optional onContextMenuRow prop, ReportsHighlightsPage
  renders ContextMenu + AddKeywordDialog on right-click
- TransactionTable: optional onRowContextMenu prop on each <tr>; TransactionsPage
  handles it and opens the dialog pre-filled with the row description + current
  category
- Aggregate tables (HighlightsTopMoversTable, ComparePeriodTable, MonthlyTrendsTable,
  CategoryOverTimeTable) are intentionally NOT wired: they show category / month
  aggregates, not individual transactions, so there is no keyword to extract from
  a row — the dialog would be nonsensical there

Fixes #75
