Story: Admin Write Operations via GroupMe
Story
As Marcus (admin), I can update player info, assign players to teams, and toggle visibility through GroupMe chat — with a confirmation prompt before any write executes.
Acceptance Criteria
- "Update Jaylen's height to 6'1" triggers confirmation prompt
- Replying "yes" executes the update and confirms success
- Replying anything else cancels the pending action
- "Add Jaylen to Kings" assigns player to team after confirmation
- "Make Jaylen public" toggles visibility after confirmation
- Confirmation expires after 5 minutes with no response
