v0.81.0

Added

• Undo for marking a loan installment paid (Budget → Loans). The one money action that creates a commitment now has the same 5-second undo as deletions — a stray tap can be taken back without hunting down the payment.

Changed

• Budget on mobile now scrolls as a single view, so the floating add button no longer covers the last category or transaction. The module tab strip scrolls horizontally with a fade hint at the edge instead of clipping the last tab, and the active tab scrolls into view.
• Budget category labels no longer truncate on tablet and desktop widths.
• Budget summary, loan, and loan-transaction surfaces are now opaque for better legibility; the glass treatment is reserved for overlays.
• Budget statistics period now shows localized dates instead of raw ISO dates.

Fixed

• Budget statistics now show a clear error state with a retry button when data can't be loaded, instead of a misleading "no data yet" message that looked like an empty history.
• Budget accessibility: category amounts carry +/− signs (not color alone), the expense-breakdown donut keeps distinct colors for more categories, loan progress is announced as a progress bar, recurring markers are labeled for screen readers, and the module tabs support full keyboard navigation (arrow keys, Home/End, roving focus).
