Wire the app to the shared Supabase catalog (public catalog read integration)

Moves port/cable/category/device-template data from per-diagram embedded
storage to the global public/private catalog backed by Supabase, per
organized-ideas.md's "live reference, not snapshot" decision.

- domain/types.ts, project.ts, compatibility.ts, bom.ts: lookup functions
  now take an explicit Catalog parameter instead of deriving data from
  Project — Project is reduced to just diagram-scoped fields.
- New CatalogRepository/SupabaseCatalogRepository (mirrors the
  DiagramRepository pattern) and catalogStore.ts, replacing the
  catalog-related actions that used to live in projectStore.
- device_templates gets a plain-text manufacturer column for now (the
  normalized manufacturer catalog from organized-ideas.md §3 is its own
  future pass, not blocking this one).
- domain/library.ts is no longer imported by the app — it's now only the
  source scripts/generate-seed.mjs reads to produce supabase/seed.sql.
- Swept every UI call site via tsc -b until clean; oxlint clean; 23/23
  pgTAP RLS tests still passing after a `supabase db reset`.
