Folder/branch pickers now render at the top of the input's rounded box
instead of a separate strip above it. Restyled as xs outlined buttons
matching the config selectors, always rendering the folder picker
chevron (dimmed when not editable). Removed the right-side commit/push
git action buttons and their unused imports. Scoped the bar to its
owning tab via a tabId prop so tile mode shows each tab's own folder
and disabled state independent of which tab is globally active.
