feat: Complete DB migration - Command parsing & task persistence

- Add command parsing for @SEND_EMAIL, @SEND_TELEGRAM, @UPDATE_TEAM_MEMBER, @ADD_TEAM_MEMBER
- Migrate all tasks.append() calls (13 occurrences) to use create_task() for DB persistence
- Update task routes to read from database instead of in-memory array
- Orchestrator beat now executes parsed commands (email/telegram notifications)
- Maintain legacy task_queue compatibility for email processing
- All tasks now persist across app restarts
