The dashboard demo-data banner is shown to Owner and Manager, but the /demo/seed endpoint required strictly Owner, so a Manager clicking it got a silent 403 (the banner had no error handler) — appearing as 'nothing happens, no tables or items'. The endpoint now allows Owner or Manager, and the banner shows the error on failure.

Adds POST /api/cafes/{cafeId}/demo/seed (owner-only) that seeds:
- 9% default VAT tax
- 7 menu categories + 59+ items via DemoMenuSeeder
- 15 inventory ingredients (coffee shop staples)
- 10 tables across 3 floors on the first active branch
Frontend DemoDataBanner appears on menu, tables, and inventory
pages when the café is completely empty, so owners can populate
demo data in one click instead of entering everything manually.
