0.7.0 - Allow limited custom style injection and remove other unused bits ☘️🥼

Custom Styles Injection

Added support for custom styles injection, similar to room-summary-card. Users can now inject custom CSS properties into specific parts of the card via YAML configuration:

• Card styles: Apply custom CSS to the main card container
• Section styles: Apply custom CSS to collapsible sections (switches)
• CSS variable: New --user--section--caret--display variable allows users to control the visibility of section carets (e.g., set to none to hide them)

Example configuration:

type: custom:adguard-card
device_id: your_device_id
styles:
  card:
    border-radius: 20px
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%)
  section:
    --user--section--caret--display: none
    background-color: rgba(0, 0, 0, 0.1)

Removed Footer Section

Removed footer section (refresh time and version updates) as these features are not applicable to AdGuard integration. This removes a random horizontal bar that shows at the bottom :)

Removed Card Actions/Controls Section

Removed the card actions/controls section entirely as it's not applicable to AdGuard card. This includes:

• Removed controls configuration option from the card config
• Removed action buttons section (previously displayed button entities)
• Removed actions from collapsible sections options
• Removed actions from exclude sections options
• Removed all related translations, styles, and tests

The card now focuses solely on displaying switches for toggling AdGuard filtering, statistics, sensors, and other relevant information without the action buttons functionality.
