feat: batch-cook shopping list (already worked) + leftover expiry reminders

Shopping list add already worked generically for batch-cook recipes —
no code needed there.

New: mark a specific batch-cook dish as "cooked today", track its
fridge expiry (cookingHistory.batchDishId), surface a "Leftovers
expiring soon" widget on the pantry page, and send a daily push+email
reminder via a new /api/internal/cron/leftover-reminders endpoint
(mirrors the weekly-digest cron pattern; doesn't use the social
notifications table, which requires a non-null actor and isn't built
for self-reminders).

Also fixes, from user-reported bugs:
- Recipe cards showed no batch-cook badge/dish-count/prep-time in some
  views — added dishCount + prepMins/cookMins (now generated by the AI
  and persisted) to the card component and /recipes query.
- Batch-cook descriptions occasionally contained raw markdown
  (**bold**) — added explicit "plain prose only" prompt instructions
  and a stripMarkdown() defensive fallback at render time.
- Truncated/cut-off descriptions — the generateObject call had no
  maxOutputTokens set, so long structured responses could get cut off
  mid-field; now capped explicitly at 8000.
- Generate dialogs (batch-cook + the main AI dialog) could show
  buttons unreachable once the progress bar appeared mid-generation —
  restructured so the action row is pinned outside the scrollable
  content area, not affected by content height changes.
- /api/internal/* routes were being redirected to /login by middleware
  before their own CRON_SECRET check ever ran (pre-existing bug,
  affected the weekly-digest cron too) — added to PUBLIC_PATHS.
