📄 Description

The /api/models endpoint previously embedded full base64 icon data inside every action/filter object on every model. With N models sharing M actions, this duplicated each icon blob N times in the JSON payload — easily tens of megabytes in setups with many models and custom actions.

Replace inline base64 data URIs with lightweight URL references to a new GET /api/v1/functions/id/{id}/icon endpoint that serves the icon binary with cache headers. The response shape stays { data: [...] } — fully OpenAI /v1/models compatible.

Changes:

Backend (models.py): Add _resolve_icon/_get_raw_icon helpers that replace data URIs with endpoint URLs and provide an is_svg flag
Backend (functions.py): Add GET /id/{id}/icon endpoint serving icon binary with 24h cache headers
Frontend (ResponseMessage.svelte): Use action.is_svg flag for dark-mode inversion instead of inspecting the data URI string
