fix: accept ES256 (ECC P-256) JWT keys alongside RS256 in backend auth

Supabase JWT key was switched to ECC P-256, but the JWKS verification
only accepted RS256. Add ES256 to the accepted algorithms list.

title: Support ES256 (ECC P-256) JWT keys in backend auth
status: in-progress

Backend JWKS verification only accepts RS256 algorithm, but Supabase JWT key was switched to ECC P-256 (ES256). This causes 401 errors on all authenticated requests. Fix: accept both RS256 and ES256 in the algorithms list, and update tests accordingly.
