feat(properties): prepare property commands before execution

- Create missing note files before running property:set.
- Default date-only datetime values to midnight.
- Keep property names out of path authorization checks.
- Split policy, vault, daily note, and command target helpers.
- Split n8n node args, description, output, and API response helpers.
- Split API tests by auth, command, daily note, and property behavior.
- Bump API and n8n node versions.
