Add 17 features: My Work view, card copy/numbering, calendar, bulk ops, custom fields, automations, webhooks, invites, import/export, and more

Features implemented across 6 batches:
- Batch A: Fix ColorPicker gradient sync, tenant custom logo, unarchive cards, board backgrounds
- Batch B: My Work view, card copy/duplicate, card numbering (BOARD-123)
- Batch C: Due date reminders (cron), card watching with notifications
- Batch D: Bulk card operations, column sorting, calendar view
- Batch E: Invite by link, board import/export (Pounce + Trello JSON)
- Batch F: Webhooks with HMAC signing, custom fields, automation rules engine
