v1.7.0: remove unreliable price data

[ch-bas]

Removed:

• All MSRP price fields (msrp_usd + localized msrp_eur/gbp/inr/aed/aud/ cad/vnd/chf) from the schema and stripped from 468 cameras. The data was sparse (~36%, single-currency, undated) and unreliable — omitting it is more honest than publishing inaccurate prices.

Changed:

• Clarified that video.streams[] describes stream capabilities, distinct from configs.frigate.* (the RTSP URLs to use) — they complement.

Docs: README schema table + roadmap updated; JSON-Schema-in-CI marked done.
