refactor(storefront): replace supabase shim in storefront pages

The legacy lib/supabase.ts shim returns { data: null } for every query,
which silently broke the tuxedo and indian-river-direct storefronts:
they displayed 'No stops on the calendar just yet' regardless of the
real data in Postgres.

Added src/actions/storefront.ts as a new "use server" module with
typed actions that hit the shared pg pool directly:
  - getStorefrontData(slug) — brand + stops + products in one call
  - getStorefrontStopBySlug(slug) — single stop + its products
  - getStorefrontWholesaleSettings(slug) — public invoice/business info

Updated to use these actions instead of the shim:
  - src/app/tuxedo/page.tsx
  - src/app/tuxedo/stops/[slug]/page.tsx
  - src/app/tuxedo/contact/ContactClientPage.tsx
  - src/app/indian-river-direct/page.tsx
  - src/app/indian-river-direct/stops/[slug]/page.tsx

The shim file itself is still imported by other pages and API routes
that will be migrated in follow-up steps.
