Refactor: move public storefront stop data to server-side + parallel agent work

Server-side / caching refactor (Grok):
- New RPC get_public_stops_for_brand (migration 148) for public storefront stops
- New server action getPublicStopsForBrand with revalidate=300 + tags
- Add revalidateTag invalidation to createStopsBatch + publishStop
- Convert /tuxedo/stops and /indian-river-direct/stops to Server Components
- Extract TuxedoStopsList + IndianRiverStopsList as client islands (GSAP only)
- Removes supabase-js from browser bundle on those routes
- Both pages now statically prerendered (5m ISR)

Parallel agent changes also staged:
- AI provider model list refresh (claude-sonnet-4-5, etc.)
- ESLint directive patches for react-hooks/set-state-in-effect
- Admin + storefront + checkout + cart updates
- New admin_create_stop_rpcs migration (147)
- Misc fixes across ~90 files

Build verified: typecheck clean, lint clean on new files, production build succeeds.
