fix(gateway): abort subsystem tasks on shutdown to avoid GW-1400 watchdog (#779)

The shutdown `select!` arm only cancelled the health monitor and broke
out of the reconnect loop, leaving `frame_loop`, `ble_loop`,
`grpc_handle`, `ble_controller`, and the modem reader task orphaned.
The tokio runtime teardown then blocked on these futures until the
5-second GW-1400 force-exit watchdog fired.

Mirror the existing cleanup from the normal-disconnect path into both
terminal-exit arms (shutdown signal and unrecoverable gRPC failure):

1. `ble_controller.cancel_and_wait().await`
2. `health_cancel.cancel()`
3. Abort and await `frame_loop`, `ble_loop`, `grpc_handle`, `health_handle`
4. `transport.abort_reader_and_wait().await`

Fixes #777
