fix(validation): cap endpoint/peer port regex at 65535

Replace \d{1,5} (0-99999) with a bounded 0-65535 matcher in the grpc,
grpc-web and peer patterns of checkEndpointAddressFormat. Addresses
Greptile review note: ports 65536-99999 previously passed validation.
Registry-wide scan confirms zero valid entries affected.
