fix(frontend): make Supabase anon key optional to unblock PyPI publishing (#589)

PyPI publishing had been broken since v1.0.3.dev851: #587 made VITE_SUPABASE_ANON_KEY a hard build-time requirement, but no such secret exists, so the frontend build aborted every publish run before the PyPI upload. Decouple package buildability from the leaderboard credential: a missing anon key now disables the savings leaderboard at runtime instead of failing the build, and auto-enables when the secret is provided. Verified: npm run build with the key unset succeeds; tsc + vitest pass.
