Fix jury reminders, add notify jurors button, fix checkbox borders, widen assignment modal

- Send Reminders button now works: added sendManualReminders() that bypasses
  cron-specific window/deadline/dedup guards so admin can send immediately
- Added Notify Jurors button that sends direct BATCH_ASSIGNED emails to all
  jurors with assignments (not dependent on NotificationEmailSetting config)
- Fixed checkbox component: default border is now neutral grey (border-input),
  red border (border-primary) only applied when checked
- Widened Add Assignment dialog from max-w-2xl to max-w-3xl to prevent overflow
