Remove reverse tunnel when proxy is deactivated

[vdanti]

[ISSUE]

In the current codebase, a reverse tunnel is established (on real devices only) during the Wi-Fi proxy configuration:

However, this reverse tunnel is never cleared, causing it to remain active on the device even after the session ends. This leads to an accumulation of "zombie" tunnels, as shown in the adb reverse --list output below:

This list will continue to grow until the device is physically reconnected or the ADB server is restarted. This can eventually lead to port conflicts or connectivity issues in subsequent test sessions.

[SOLUTION]

Implement a new function removeReverseTunnel in adb.ts to remove the specific reverse tunnel matching the TCP port used during setup.

Integrate this cleanup logic into the deleteSession and onUnexpectedShutdown hooks in plugin.ts to ensure the device environment is restored to its original state, regardless of the test outcome.
