### What is the motivation behind this feature request? Is your feature request related to a problem? Please describe.

Have an easier way to cancel deals / stop trying to make a storage deal if an fvm contract deal has already been claimed by another SP.

### Describe the solution you'd like

SP suggestion (from early fvm testing) : It would be nice for boost to make cancel deals & clear the deal from the queue if the deal has been claimed by others

### Describe alternatives you've considered

_No response_

### Additional context

_No response_

No files or tests are named. Start by tracing the boost daemon's storage-deal queue and its FVM contract-deal handling, then check how the boost UI exposes queued deals. Done means an already-claimed deal can be cancelled and removed from the queue without further storage-deal attempts.
