feat: Add contract lifecycle management commands (complete and resume-contract)

Add supervisor commands for properly managing contract lifecycle:
- `makima supervisor complete` - Mark a contract as complete and stop the supervisor
- `makima supervisor resume-contract` - Resume a completed contract (reactivate it)

Also adds `api_key` field to TaskConfig for authenticated API calls.

This consolidates the lifecycle management features from the contract-lifecycle-cleanup branch.
