feat(auth): add authentication protocol definitions and build configuration
- Add TokenClaims message for JWT payload structure with user id, issuer, timestamps, and scopes - Implement IssueTokenRequest/Response for creating access and refresh tokens with TTL support - Create RefreshTokenRequest/Response for token rotation functionality - Define RevokeTokenRequest/Response with support for single token or user-wide revocation - Add VerifyTokenRequest/Response for validating JWT tokens with detailed claims information - Implement signing key distribution system with GetSigningKeysRequest/Response - Create TokenService gRPC service with IssueToken, RefreshToken, RevokeToken, VerifyToken, and GetSigningKeys methods - Add build.rs configuration to compile proto files using tonic_prost_build - Include channel, channel_settings, member, and permission protocol definitions for IM services - Generate Rust code bindings through pb/core.rs and pb/im.rs modules
