ci: exclude Deno edge functions and migration tests from web eslint

The web ESLint config (browser/React rules: no-explicit-any, no-unused-vars)
was linting supabase/functions/** and supabase/migrations/** — Deno TypeScript
that legitimately uses `any` for the chain/Supabase surfaces and npm: imports.
These have their own tooling (deno check + deno test) which passes. Add both
dirs to ignores so `eslint .` covers only the Vite app it is configured for.
