Bridge global catalogue DB to per-store product catalogue

Adds a separate CatalogueDB (pgvector) connection alongside the main
nearledb, plus a new catalogue module (repository/service/controller/
routes) to browse it by brand, category, and keyword, with brand
optional so the whole ~237-product catalogue can be browsed unfiltered.

Adds the actual bridge: importing a catalogue product snapshots it into
the tenant's own products table (keyed on brand+catalogueid, since a
catalogue row's bare id is only unique within its own brand table),
then links it via the existing productlocations upsert. Re-importing
tops up stock and refreshes price instead of duplicating. Also adds an
imported-refs endpoint so the frontend can badge already-imported items
without diffing full product lists, and wires the new AWS S3 image
store used to resolve catalogue product photos.

Bumps Go/Docker to 1.24 for the AWS SDK dependency this needs.
