Fix nil pointer panic in ICE agent during sleep/wake cycles (#5261)

Browse Source 
Add defensive nil checks in ThreadSafeAgent.Close() to prevent panic
when agent field is nil. This can occur during Windows suspend/resume
when network interfaces are disrupted or the pion/ice library returns
nil without error.

Also capture agent pointer in local variable before goroutine execution
to prevent race conditions.

Fixes service crashes on laptop wake-up.
