Send one alert to every screen, teach Claude about ESP Screens, and add a Settings page (0.2.45)

- The app listens for the Home Assistant events esp_screens_show_alert and
  esp_screens_dismiss_alert and calls each screen's show_alert/dismiss_alert action,
  screens added later included. Fields are typed like Home Assistant's ESPHome action
  schema; an unusable value is left empty instead of losing the alert.
- Settings → Claude installs an ESP Screens skill for Claude Code in Home Assistant
  (/homeassistant/.claude/skills/esp-screens) or downloads it as a zip for claude.ai.
  It is generated from the alert reference, so fields, colors and icons match the firmware.
- New screen, Firmware & USB, firmware updates, Alerts and Claude move to a Settings view;
  the header keeps one button. Unselected screens in My screens get a light grey card.

App only; firmware stays 0.2.38.
