The official-bots service enabled smallrye-jwt but never set
mp.jwt.verify.publickey.location or issuer, so it could not validate
any incoming token and rejected every authenticated request with 401.
Add the verify public key (issuer nowchess) mirroring tournament/core,
and ship keys/public.pem from the shared keypair.
