fix: bitbucket pullrequest updates don't update preview deployments b…

…y replacing repo:push with pullrequest:updated in bitbucket webhook hander

Bitbucket's repo:push webhook doesn't provide the destination branch name in new commits, 
which prevents Coolify from finding the correct application to update preview deployments. 
By switching to pullrequest:updated and only processing updates due to new commits, 
we can reliably get the correct branch name that matches the Coolify application, 
ensuring preview deployments are properly updated.

- Remove repo:push event handling in favor of pullrequest:updated
- Add check to ignore PR updates not related to new commits
- Update handled_events collection to reflect new webhook strategy

Closes coollabsio#2793
