Update pr after creation (#492)

* feat: allow pushing updates to open PRs (#470)

PR push after creation (vibe-kanban c22efac9)

In the last commit, we added the ability to push new changes after a PR has been created. Is there a good way to only show this if there are actually new changes?

feat: allow pushing updates to open PRs (#470)

Commit changes from coding agent for task attempt 771ed0db-8c90-4556-b732-5888b665c42b

refactor: simplify unpushed commits check by focusing on origin/branch_name

PR creation review (vibe-kanban 89c2ecdd)

In the last two commits, we added the ability to push new changes after a PR has been created.
Please review this and explain potential shortcomings

* Fix git push frontend

* Use GitService provided by deployment

* Fix ssh auth failing blocking BranchStatus request

* Fix refspec

* Fix frontend to reflect disconnected
