* feat(providers): editable ComfyUI base-URL field + per-connection override for image/video/music generation (#6928)
Adds a shared resolveComfyUiBaseUrl() helper (open-sse/utils/comfyuiClient.ts) that
prefers a per-connection providerSpecificData.baseUrl override over the registry
default, wired through the comfyui dispatch branch in the image, video, and music
generation handlers plus a best-effort authType:"none" credential lookup in all
three /v1/{images,videos,music}/generations routes (never hard-fails when no
connection exists, so zero-config localhost users are unaffected).
Surfaces an editable base-URL field on the ComfyUI connection form by adding it to
CONFIGURABLE_BASE_URL_PROVIDERS / DEFAULT_PROVIDER_BASE_URLS /
getProviderBaseUrlPlaceholder in providerPageHelpers.ts, so Docker-network setups
(e.g. http://comfyui:8188) can be configured the same way self-hosted chat
providers are.
Closes#6928
* refactor(6928): extract local-override credential lookup in media routes
The inline per-connection override block nested if>if inside the music and
videos POST handlers, taking each to cognitive complexity 16 (>15) — two NEW
violations that broke check:complexity-ratchets (892 > baseline 890).
Extracted resolveLocalOverrideCredentials() in both routes; behaviour is
unchanged. cognitive-complexity back to 890 = baseline.
Add 6 TTS providers (Nvidia NIM, ElevenLabs, HuggingFace, Coqui, Tortoise,
Qwen3), 3 STT providers (Nvidia NIM, HuggingFace, Qwen3), 2 local image
providers (SD WebUI, ComfyUI), and two new modalities — Text-to-Video
(/v1/videos/generations) and Text-to-Music (/v1/music/generations).
Key design decisions:
- Format-based unified providers: local providers grouped by API format
(comfyui, sdwebui, coqui, tortoise, openai-compatible) with configurable
base URLs and expandable model lists
- Cloud providers kept separate (unique auth and API shapes)
- Local providers use authType: "none" — credential checks bypassed at both
route and handler level
- Shared ComfyUI client (comfyuiClient.ts) reused across image/video/music
- Shared registry utilities (registryUtils.ts) for model parsing and listing
- Qwen3 TTS/ASR use format: "openai" — no custom handler needed
