feat(auth): add interactive key policy editing

- Add auth policy to update existing authorized_keys allow policies locally or over remote serve.
- Support key lookup by public key or exact name, with safe, all, server-default, and category-based modes.
- Add questionary-powered interactive key selection and checkbox policy editing with current policy preselected.
- Show policy descriptions in auth keys output so each capability is easier to understand.
- Gate the new remote control command behind the existing keys policy category and include protocol routing/compat updates.
- Bump real-browser-cli to 0.16.2 and lock the new questionary dependency.
- Cover local, remote, validation, and policy-category behavior in tests.
