TICKET-005: Frontend daily view — milestone M1 complete

- Dashboard: progress bar vs target, entries grouped by meal slot,
  edit/delete inline, date navigation (UTC-safe shiftDate helper)
- Add Food manual creation form, search-and-log flow with live preview
- Minimal target form; loading/error/empty states throughout
- Stores (current date, log, summary) with summary refresh on mutation
- All HTTP via lib/api.js; formatting via lib/format.js; runes only
- Full suites green (backend 104 passed, frontend vitest + build)
