reload_dshackle.sh: drop established gRPC connections after successful SIGHUP reload

Browse Source 
Extend reload_dshackle.sh to drop established gateway gRPC connections on
port 2449 after a successful SIGHUP config reload, forcing the dRPC edge
to reconnect within ~1s and re-read the advertised chain/method list.
Gateways only re-initialize advertisements on reconnection (verified live:
0.03-0.06s serving gap, 33 re-probes in 4s). This allows deploy-time upstream
additions (new chains like mova, new backends like us-50) to be seen by
dRPC immediately rather than waiting for natural reconnection.

The TCP-level drop is best-effort: failure does NOT fail the script.
Operator ruling: this stays a TCP-level drop, NOT a dshackle code change.
