chore(worktree): drop dead otherBranches labels after search guard

The mobile and desktop (cmdk) pickers in NewWorktreeDialog now hide
non-matching branches during search via a !hasExistingBranchQuery /
!hasSourceBranchQuery outer guard. That makes the inner heading
ternaries (which switched between 'localBranches' and
'otherLocalBranches' depending on the search state) unreachable: they
always resolve to the non-query label, and the
'hasExistingBranchQuery && <CommandSeparator />' lines were dead code.

This commit:

- Replaces 8 heading ternaries with static non-query labels
  (mobile and desktop, existing/source, local/remote).
- Drops the two unreachable <CommandSeparator /> renders in the
  otherLocal blocks.
- Simplifies the otherRemote separator conditions by removing the
  always-false '|| hasExistingBranchQuery' / '|| hasSourceBranchQuery'
  terms.
- Removes the now-unused 'session.newWorktree.otherLocalBranches' and
  'session.newWorktree.otherRemoteBranches' keys from all 9 locales.

Behavior is unchanged; this is dead-branch cleanup only.
