P2: file operations with dialogs (mkdir, new file, rename, delete, chmod)

- prompt/confirm/chmod dialogs (signals-driven via DialogsService) - FileActionsService: acts on selection or cursor row of the active panel - function bar + F2/F7/F8/Delete keys; delete confirms and recurses - verified provider ops + walkTree + removeRecursive on a scratch tree Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
