v2.1.0

Added

• Frontend internationalisation (i18n). The Fado panel/card UI now loads
  per-language catalogs (frontend/translations/<lang>.json) and renders in
  your Home Assistant language, with English as the built-in fallback. Ships
  with 24 languages out of the box. Non-English UI translations are
  AI-generated and pending native review — corrections welcome.
• A dismissable banner that nudges users whose Home Assistant language Fado does
  not yet support to request a translation via a prefilled GitHub issue.
• Frontend: responsive layout — on narrow screens the lights table becomes
  collapsible per-light cards with a "needs setup" indicator and a per-area
  roll-up; touch-friendly controls.

Changed

• Frontend: configuration panel/card now use HA's themed select control and a
  --fado-* design-token layer for consistent theming.
• Panel/card UI strings are now localised via the new i18n layer (English output
  unchanged).

Removed

• BREAKING: Removed the Log level selector from the configuration panel.
  Fado logs through Home Assistant's standard logger, so adjust its verbosity
  the usual way instead — Enable debug logging on the integration page, or a
  logger: entry in configuration.yaml. See the Troubleshooting section of
  the README. If you previously raised the level via the panel, that choice is
  no longer re-applied on restart; set it the standard way to make it persist.
