chore(release): v1.9.3 — manual project & order creation (price + PO upload)

Manual standalone project creation (shared numbering pool, with tracking:
collision-safe, release-on-delete, audit, Samostatný/Z objednávky badge) and
manual order creation without an offer (header form, optional linked project,
price line item, PO PDF upload mirroring the from-offer flow). Re-adds the
projects.create permission via migration + seed.
