[bugfix/git_helper] Enable "all" option in text fallback delete_orphans checklist #9
Description
User Story: Enable "all" option in text fallback delete_orphans checklist
As a user running the Git helper script without whiptail/dialog (text fallback mode)
I want to be able to select all orphan branches for deletion at once using the 'all' keyword
So that I don't have to manually type each branch name when I want to delete all orphan branches
Acceptance Criteria:
When running the "Delete local branches not on remote" action in text fallback mode, entering 'all' at the prompt should select all available orphan branches for deletion
The 'all' keyword should be expanded to the full list of branch names before being passed to the deletion logic
The confirmation prompt should show which branches will be deleted
The behavior should match the intent of the 'all' option mentioned in the prompt text
Notes:
The text fallback UI's ui_checklist function tells users they can enter 'all', but currently returns 'all' as-is without expanding it to the actual list of options
The workaround is to manually enter each branch name space-separated
The 'all' functionality works in whiptail/dialog modes (they're graphical), but the text mode needs explicit handling
