feat(activities): split customer column, wider search, custom activity types with type-specific fields

- Table: separate assignee and customer columns; search by assignee and activity type
- ActivityTypeDef model with per-type field definitions (text, select, checklist, participants, ...)
- Default types incl. meeting subject/participants and task checklist; admins manage types
- Participants see activities in their lists and get notified
