Subject: [PATCH] fix: auto-create default branch on cafe registration +
 backfill existing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- VerifyRegisterAsync: create a Branch named after the café alongside
  the Café and Owner, so new owners can use the dashboard immediately
  without hitting the "select a branch" gate
- PlatformDataSeeder: EnsureDefaultBranchesAsync runs on every boot and
  creates a default branch for any existing café that has none (covers
  cafés registered before this fix)
