🤖 Augment PR Summary

Summary: This PR completes the Apache HttpClient 5.x (HttpComponents) migration for MiniApp/Open and makes HttpComponents the default in more modules.
Key changes:

• Added HttpComponents (Apache HttpClient 5.x) service implementations for MiniApp and Open modules (WxMaServiceHttpComponentsImpl, WxOpenServiceHttpComponentsImpl).
• Switched core default service implementations to extend the HttpComponents variants (MiniApp/MP/Qidian/Pay/Channel/Open), making HttpClient 5.x the default client.
• Updated Solon plugins and Spring Boot starters to support selecting HttpComponents and, in several modules, changed the default httpClientType to HttpComponents.
• Extended multi-tenant plugin enums to include HTTP_COMPONENTS and wired new switch cases to instantiate the 5.x implementations.
• Updated the HTTP client upgrade guide to reflect the new defaults (notably MiniApp).

Notes: HttpClient 4.x implementations remain available via explicit configuration, but defaults now bias toward HttpClient 5.x for consistency. Why: Consolidate the SDK on a modern, unified HTTP stack (Apache HttpClient 5.x). Compatibility: If you previously customized HttpClient4 builder/timeout behavior, double-check equivalent behavior under HttpComponents defaults.
