Add reordering support for budget categories and line items within
categories. Changes persist via new DB table (budget_category_order)
and existing sort_order column. Live sync via WebSocket budget:reordered
event. Use Map instead of plain objects for category grouping to
preserve insertion order with numeric category names.
Handle European number formats (e.g. 1.150,32) by detecting the last
separator as decimal and stripping thousand separators. Applied to
budget inline edit cells, add item row, and reservation price field.
Fixes#498
- Link budget items to reservations via reservation_id column
- Update budget entry when reservation price changes (not create duplicate)
- Delete budget entry when reservation price is cleared
- Sync price back to reservation when edited in budget panel
- Lock budget item name when linked to a reservation
- Add migration 73 for reservation_id on budget_items
Date-only strings parsed with new Date(dateStr + 'T00:00:00') were
interpreted relative to the local timezone, causing off-by-one day
display for users west of UTC. Fixed across 16 files by parsing as
UTC ('T00:00:00Z') and displaying with timeZone: 'UTC'.
- New expense_date column on budget items (DB migration #42)
- Date column in budget table with custom date picker
- CSV export button with BOM, semicolon separator, localized dates,
currency in header, per-person/day calculations
- CustomDatePicker compact/borderless modes for inline table use
- i18n keys for all 12 languages
- Click member avatars on budget items to mark who paid (green = paid)
- Multiple green chips = those people split the payment equally
- Settlement dropdown in the total budget card shows optimized payment
flows (who owes whom how much) and net balances per person
- Info tooltip explains how the feature works
- New server endpoint GET /budget/settlement calculates net balances
and minimized payment flows using a greedy algorithm
- Merged category legend: amount + percentage in one row
- i18n keys added for DE and EN
