fix: persist channel secrets to DB at startup for pkt_payload computation

Browse Source 
_load_channel_secrets() cached secrets in memory only. After dfc3b14
switched /api/messages to use DB channels instead of device calls,
the empty channels table caused Route info and Analyzer links to
disappear from message bubbles.

Now upserts each channel (name + secret) to DB during startup so
the API can compute pkt_payload without hitting the device.
