Enable sticky sessions on operator-created Services (#3986)

* Enable sticky sessions on operator-created Services

MCP servers use stateful session protocols (SSE, streamable-http).
When replicas > 1, Kubernetes round-robin routing breaks sessions.
Set SessionAffinity: ClientIP on all operator-created Services
(MCPServer, MCPRemoteProxy, VirtualMCPServer) so requests from
the same client consistently reach the same backend pod.

Also add drift detection in serviceNeedsUpdate() and copy
SessionAffinity in the ensureService update paths so existing
Services get reconciled.

* Update operator architecture docs for SessionAffinity

Document that all operator-created Services use
SessionAffinity: ClientIP to support stateful MCP sessions.
