v0.29.0 — Ramble box, dark-mode toggle, pantry pull reasons

- #10 Ramble box: new /ramble sticky-note board (post/pin/archive/delete),
  ported from FMB. New Ramble model + migration, /api/rambles routes, nav entry.
- #6 Dark-mode toggle: sun/moon button in the top bar (dark palette already
  existed in CSS, just had no control).
- #9 Pantry pull reason: structured disposition (Immediate use / Preserved /
  Gave away / Waste) on ItemLog.reason, added to single + bulk pull dialogs
  and the audit payload. New migration.
- #2 Suggestions: drop the stale white-card wrapper; render SuggestionsPanel
  bare like FMB so it's readable and thumbnails show.
