Rewrite on the Bennett platform: Spring Boot + Vite/React SPA

Replaces the Next.js app. Same site, same look; the parts that were decisions rather
than markup now live in Java.

- catalogue, curated order, category filter and image URLs move from a TypeScript array
  into Postgres behind /api/products and /api/categories
- contact form uses the shared platform-starter-contact: validate, RECORD, send, then
  fan out to n8n. Recording first means a relay outage costs a notification, not an enquiry
- PageMetaController rewrites title/description/OG per route, replacing what Next's SSR
  gave crawlers and link-preview scrapers
- 50MB of photos leave the repo for the MinIO bucket, re-encoded to webp (14MB) with EXIF
  (including phone GPS) stripped
- fixes a catalogue typo: 'Strawberry Pie' was category 'Pies', which no filter matched, so
  it was unreachable unless browsing All
