v0.7.0 - Browser-side transitions, visual editor, frame_id

This release adds a custom Lovelace card with smooth, browser-rendered transitions, a visual editor, and several quality-of-life improvements to the camera entity.

Transitions were inspired by a suggestion from @der-optimist on the Home Assistant forum. Thank you!

✨ Highlights

Album Slideshow Card

A custom Lovelace card ships with the integration. The integration registers it automatically - no HACS frontend repository to add and no Lovelace resource to configure. After installing or upgrading, hard-refresh your dashboard once (Ctrl+Shift+R) to pick up the script.

• Smooth slide transitions rendered in the browser, so they stay buttery even on lower-end hardware. The server only renders one still per slide change; the browser cross-fades in CSS.
• Effects: random, none, fade, slide-left, slide-right, slide-up, slide-down, wipe-left, wipe-right, zoom.
• random picks a different effect per slide and avoids repeating the previous one.
• Configurable duration and CSS easing.
• aspect_ratio, fit (auto / cover / contain), and background options. fit: auto inherits the camera's fill_mode attribute (cover / contain / blur backdrop).
• Optional tap_action: more-info opens the camera's more-info dialog.
• Visual editor available - pick Album Slideshow from the card picker in Lovelace and the form appears automatically.

type: custom:album-slideshow-card
entity: camera.album_slideshow_living_room
transition: random
duration: 800
easing: ease-in-out
aspect_ratio: 16/9
fit: auto
background: '#000'
tap_action: none

Camera

• New frame_id attribute: a monotonic counter that increments on every committed slide. The card uses it to cache-bust the camera proxy URL so a fresh JPEG is fetched on every slide.
• The camera's entity_picture URL now appends &frame=<frame_id>, so any picture-entity cards or templated entity_picture consumers also see fresh frames per slide instead of stale browser-cached images.
