## Changes
- **Prompt character counters on web**: the website and webapp
promptboxes (image + video) now show a `123 / 2000` counter driven by
the API's `text_prompt_max_length`, matching the desktop app. It turns
red when over the limit and generation is blocked with a toast; typing
is never clamped. The webapp's fullscreen prompt editor shows the
counter too.
- **Seedance CJK waiver**: seedance video models normally use the API
limit, but the limit is waived (shows `∞`) while the prompt contains
Chinese characters. Applies on desktop and web via a shared
`effectivePromptMaxLength` helper.
- **API type parity**: added the new `model_creator` field to the web
`OmniGenImageModelInfo` / `OmniGenVideoModelInfo` types (desktop types
were already up to date).
- **Cleanup**: deleted the manual model-to-creator map
(`MODEL_TYPE_TO_CREATOR`, ~150 lines) now that creator info comes from
the API; lightbox model icons use the shared
`getCreatorIconPathForModelId` lookup like every other surface.
