Adds an "Editor Posizione" button to the furni infostand action bar for
branding / MPU furni, opening a dialog to position and zoom the image:
- draggable dot moves offsetX/Y (live, local preview only)
- slider zooms the image (scale, via the renderer's per-sprite scale)
- offsetZ kept as z-index; Save persists + broadcasts via SetObjectData
- radio "Live" + all editor labels go through LocalizeText (external texts)
Pairs with the renderer branding scale/offset support and Arcturus' `scale`
default on InteractionRoomAds.
Adds a compact collapsible radio widget (top-left) that plays internet
radio streams with the HTML5 Audio API — no server/renderer changes.
- station list loaded from a JSON5 config file (loadGamedata: JSON + JSON5),
shipped as radio-stations.json5.example so each hotel fills in its own
- shows the selected station + a dropdown (3 visible, scrolls if more) to
switch; volume slider; animated equalizer + LIVE indicator
- first station autostarts quietly (5%) on load, with a resume-on-first-
gesture fallback for browser autoplay policy
