fix(lunch): reminder filter, recap failure surfacing, manual send-reminders

- Extract selectUnpickedAttendees helper with OR filter (is null OR pickedAt null)
  to fix cron missing attendees with no MemberLunchPick row at all
- Update cron route to use the helper
- sendRecap now throws TRPCError on email failure instead of silently stamping success
- Add lunch.sendReminders adminProcedure for manual on-demand reminder sends
- Add "Send reminders now" AlertDialog button to LunchRecapActions
- Tests: lunch-reminder-filter.test.ts (2 new), all 5 lunch test files pass (40 tests)
