Remove remaining Supabase clients and drop @supabase/supabase-js (#90)

* Remove remaining Supabase clients and drop the dependency

- Delete RecentTradesDataLayer.jsx (never rendered in prod: ENABLE_SUBGRAPH_FOR_ALL_PROPOSALS forces the subgraph path)
- Strip Supabase client + candle/trade fetch paths from MarketPageShowcaseViewModel and MarketHistoryViewModel (subgraph/SQL-direct paths kept)
- Remove @supabase/supabase-js from package.json and lockfile

Netlify prod env has no Supabase vars, so all removed code was dead weight.
scripts/generate-seo.mjs still references Supabase but only runs via the
optional build-with-seo script; replacing it with a registry-fed generator
is tracked separately.

* Update auto-qa baselines: supabase imports 10→0, GNOSIS_RPCS 5→4

The supabase ratchet fired as designed (this PR removed the last 10
imports). The GNOSIS_RPCS count went stale on main when #89 dropped the
dead Blast entry after the auto-qa suite (#75) pinned it at 5.
