ADDED - Save an unfinished project as a draft

- Add a Save as draft button that bypasses the completeness gate: the user
  can save partial work and finish later
- projectDraftInputSchema makes the user-facing copy (title, summary, service
  label, client) optional; the action auto-generates a slug from the title
  (or draft-<timestamp>), defaults the year to the current year, and forces
  the project unpublished
- Drafts drop not-yet-valid sections/assets instead of failing the save
- Pass intent via a hidden field set on click so the server reliably sees it
- Tests: draft schema accepts empty copy a strict save rejects, and still
  requires a slug and a valid year
