Volunteer Management Lifecycle

[vivjd]

Goal:
Refine the administrative workflow for managing volunteer access and expirations.

Tasks:

• Fix the "Renew/Extend" button in the volunteer management view.
• Update the volunteer approval form to include an "Expiry Date" field. This can include a default values of no expiry date if needed, but it needs to be manually set.
• Ensure the backend correctly updates the access_expiry timestamp upon extension.

Acceptance Criteria:

• Admins can specify an expiration date when approving a new volunteer.
• The "Renew/Extend" button successfully increments the existing access period.
