chore: refactor agent routines that use the v2 API (#12223)

Browse Source 
In anticipation of needing the `LogSender` to run on a context that doesn't get immediately canceled when you `Close()` the agent, I've undertaken a little refactor to manage the goroutines that get run against the Tailnet and Agent API connection.

This handles controlling two contexts, one that gets canceled right away at the start of graceful shutdown, and another that stays up to allow graceful shutdown to complete.
