refactor: migrate to Alamofire and improve HTTP layer

- Add AlamofireExtensions for HTTP client abstraction
- Remove deprecated HTTP layer components (HTTPRequest, HTTPResponse, SessionAdapters)
- Rename HTTPFields to HTTPHeadersExtensions for clarity
- Update Auth, PostgREST, Realtime, and Storage modules to use new HTTP layer
- Remove unused test files and clean up dependencies
- Update documentation with final test coverage summary
- Clean up deprecated code and improve code organization
