Make the proxy activity timeout configurable and document streaming

[woksin]

Summary

The idle limit AuthProxy applies to proxied requests, WebSocket sessions and Server-Sent Events streams is now configurable, and the documentation describes how streaming behaves through the proxy.

Added

• ActivityTimeout at the root (Cratis:AuthProxy:ActivityTimeout), per service under Services and per Backend/Frontend endpoint; the most specific value wins and the default stays five minutes. Values must be between one millisecond and 2,147,483,647 milliseconds (about 24 days), inclusive; values outside this range stop AuthProxy at startup with a message naming the setting. (Make the proxy activity timeout configurable and document streaming (WebSocket, SSE) #153)
• Unsupported activity timeout settings stop AuthProxy at startup with a message naming each setting: Registration:ActivityTimeout and ActivityTimeout on Invite:Lobby or any of its endpoints. Remove these settings and configure the proxied service's Backend or Frontend timeout under Services instead. (Make the proxy activity timeout configurable and document streaming (WebSocket, SSE) #153)
• Aspire WithActivityTimeout and WithServiceActivityTimeout to set the limit from an app host. (Make the proxy activity timeout configurable and document streaming (WebSocket, SSE) #153)
• Documentation of streaming through AuthProxy: heartbeats, interaction with platform idle limits, and when a stream is authorized. See Timeouts and streaming. (Make the proxy activity timeout configurable and document streaming (WebSocket, SSE) #153)
