v0.3.1

Added

• Card: group_sort_by option for combined group cards — sort the group breakdown table by name_asc (default), name_desc, or offline_desc (most offline first, ties broken by name)
• Card editor: Sort Groups By dropdown shown when a combined group is selected; replaces the entity sort controls that are not applicable to combined groups
• Debug logging across coordinator, sensor setup, and storage — enable with logger: logs: custom_components.entity_availability: debug in HA configuration; logs cover state transitions, cooldown/offline/recovery events, suppression changes, battery detection source, storage load/save, and availability bucket lifecycle

Fixed

• Card: fixed iOS Companion App "configuration error" — replaced customElements.whenDefined("ha-panel-lovelace") (lazy-loaded, may not fire on iOS WKWebView) with a multi-element bootstrap that tries home-assistant-main first (always in HA's initial bundle), falling back to ha-panel-lovelace and hui-view; also tries element registration immediately if any anchor element is already defined
• Card: html/nothing/css are now sourced from both the constructor and prototype to handle variation across HA bundle builds
• Card editor: group dropdown was empty when the config entry was renamed to remove the "Entity Availability" prefix — sensors now register with stable entity_availability_ prefixed entity IDs regardless of entry title, so the card can always discover them; note: applies to new installs only — existing installs with already-renamed entries need to delete and re-add the integration to get stable IDs
