fix: resolve SessionWatcher goroutine leak and unstable UT in querycoordv2 (#45627)

Related to #44620
Related to unstable ut "internal/querycoordv2 TestServer/TestNodeUp"

Introduce SessionWatcher interface to fix race condition and goroutine
leak that caused unstable unit test TestServer/TestNodeUp.

Changes:
- Add SessionWatcher interface with EventChannel() and Stop() methods
- Refactor WatchServices() to return SessionWatcher instead of raw
channel
- Fix cleanup order in QueryCoordV2: stop watcher before session
- Update DataCoord, ConnectionManager to use SessionWatcher
- Add MockSessionWatcher for testing

Fixes race condition between session context cancellation and internal
loop exit. Eliminates goroutine leak by providing explicit lifecycle
management.
