Pull request overview

This PR updates major HTTP client dependencies to their latest versions, primarily upgrading rustls from 0.21 to 0.23, reqwest from 0.11 to 0.12, and oauth2 from 4.4 to 5.0. The changes adapt the codebase to breaking API changes in these libraries, particularly around TLS configuration, certificate verification, and OAuth2 client initialization.

Key Changes:

• Migrated to rustls 0.23's new crypto provider model with aws-lc-rs as the default provider
• Updated ServerCertVerifier trait implementation to include new required signature verification methods
• Refactored OAuth2 client initialization to use builder pattern instead of constructor parameters
• Modified test expectations to reflect new error handling behavior with fallback to defaults
