Finalize GPL-3.0 licensing and openScale attribution

- Replace the shortened LICENSE with the complete official GPLv3 text.
- Rewrite the README License section: project is GPL-3.0, openScale
  (RealmeSmartScaleHandler / YunmaiLib) attribution preserved, and the
  project is an independent community project (no affiliation claims).
- Add consistent GPLv3 copyright headers to every distributed component
  module.  bia.py and scale_controller.py carry the verified upstream
  openScale copyright notice (C) 2025 olie.xdev in their headers;
  all other modules are original realme-scale-ha code, Copyright (C) 2026
  Kapil Mahawar.
- No functional changes; only comments/headers/docs/LICENSE.
