Close the LLM data gaps: add build_satpass_detail (satpass_events was written
but had no reader), and give avalanche + ducting durable tables (v24/v25) with
native writers + env_reporter readers so the mesh LLM can answer avalanche,
satellite-pass, and RF-propagation questions. Persistence-only; no broadcast/
gating changes.
