Budget: unify transactions section into one card

Toolbar (source tabs, search, CSV, add) and a summary strip (billing
cycle range, count, per-currency total) now live inside the table card
instead of five loose control rows. Cycle range 18-to-18 is finally
visible. Stray English strings translated; back-button spacing fixed.
