fix: stabilize worktree branch selector popovers

[kirillk]

Summary

• render the worktree branch selector popovers inline so the dialog focus trap no longer blocks the search input
• autofocus the branch filter field when the popover opens and move branch selector inputs to shared data-autofocus behavior
• keep the branch selector popovers anchored above the trigger without flipping as filtered results change size
