Make environmental feeds band-agnostic; add Environment page

- Remove band_assessment and band_detail from SWPC adapter
- Remove all frequency-specific conclusions (906 MHz, 10m-20m, etc.)
- Store only raw indices: SFI, Kp, R/S/G scales, dM/dz gradients
- Let LLM interpret propagation data based on user's band of interest
- Add full Environment page with feed status, solar indices, and ducting data
- Update Dashboard RF Propagation card to show raw values only
- Update alert messages to be frequency-agnostic
