feat: Add channel, boot count, RSSI min/max, actual CSI rate to STATUS

Browse Source 
- WiFi channel in STATUS (channel=)
- Boot counter persisted in NVS (boots=)
- RSSI min/max tracked from CSI frames since boot (rssi_min=, rssi_max=)
- Actual CSI rate computed from csi_count/uptime_s (csi_rate=)
