UI fixes

🧢 Changes

I fixed 3 UI/UX issues I encountered:

• I kept trying to drag changes onto the 'big' folded out commit panel on the right side of the stack but that wasn't a drop area
• I found it confusing that I can change branch names by clicking them in the header but not commit titles
• I ran into a small bug where switching between repos gives a wrong github integration popup

@mathijs81 is attempting to deploy a commit to the GitButler Team on Vercel.

A member of the Team first needs to authorize it.

• Adds drop zone support to the expanded commit details view for amending/squashing commits
• Makes commit titles clickable to enter edit mode, improving discoverability

@mathijs81 thank you for the PR!

I found it confusing that I can change branch names by clicking them in the header but not commit titles

Let’s move this item to a separate PR because it’s not about fixing a bug but adding a new feature.

I moved the commit title change to a different PR.
Here's a video that shows how you can't drop a file onto the commit details pane in the current version
and when switching to my "Gitbutler Dev" it does work:
