Reduce log noise: suppress ASP.NET/HttpClient info logs, render messages, silence ChatMember updates (#111)

- Override MinimumLevel to Warning for Microsoft.AspNetCore and System.Net.Http.HttpClient
  (incoming/outgoing HTTP request lifecycle logs are redundant with OTEL traces)
- Switch CompactJsonFormatter to RenderedCompactJsonFormatter so logs contain
  readable @m instead of raw @mt template
- Handle ChatMember/MyChatMember updates silently instead of logging a warning
