refactor(libra): redesign transactions list status + type encoding

Rework how the standalone transactions list communicates entry status
and type so each visual channel does one job and the filter UI matches
the underlying axes.

Encoding:
- Type lives in the signed/colored amount (+green income, -red expense)
  and a matching Income/Expense badge in the badge row.
- Status lives in badges only: red Voided (leftmost) and yellow Pending
  (after the type badge). Cleared entries carry no status badge — the
  quiet default.
- Voided rows additionally strike-through and mute the amount.
- Drop the title-row status icons and the colored left border that
  previously fought with the amount color for the same meaning.

Filter UI:
- Replace the type radio + voided switch with three category chips —
  Income, Expenses, Voided — that independently toggle inclusion of one
  bucket of rows. Each row belongs to exactly one bucket (voided wins
  over type). Defaults: Income + Expenses on, Voided off.
- Empty-selection state nudges the user to enable a category.
