HYBRID CALENDAR 5.9.0 — BOARD INTEGRATION

- Preserves the complete 5.8.0 calendar interface and working task functions.
- Adds an optional secured Board context without creating another calendar design.
- Every Board request rechecks logged-in CRM identity and active Board membership.
- Assignment choices use active members of the current Board, not every CRM staff record.
- Each staff member continues to own a personal calendar; Board tasks are tagged and isolated by Board.
- Existing personal calendar records remain in the default personal context.
- Board actions import once and remain linked through board_action_id.
- Calendar completion updates the linked Board action.
- Board scheduling updates the same linked calendar card.
- Assigning a task creates a native CRM notification for the assigned staff member.
- Workforce/HR and central user creation remain separate administrative authorities.
