docs: AI video trial restriction and Veo3 to Seedance 2.0 rename

[giladresisi]

⚠️ DO NOT MERGE until gitroomhq/postiz-app#2062 is deployed

The trial disclosure this PR documents is only visible in the app once that change is live. The Veo3 to Seedance 2.0 rename is already true in production, but the pages are edited together so they should ship together.

What kind of change does this PR introduce?

Documentation (composer guide, Cloud plans page, MCP tools reference, Public API OpenAPI). Two things:

1. Trial restriction. general/composer/ai-and-imports.mdx says Seedance 2.0 is paid plans only on Cloud and held back during the 7-day trial, while Image and text slides works during the trial. cloud/plans.mdx adds one sentence to the credits paragraph saying only trial-available generators (currently Image Text Slides) can be used during the trial. mcp/tools.mdx adds a line under generateVideoTool about the HTTP 406 This video is not available in trial mode response, and public-api/openapi.json gets a 406 response on POST /generate-video with the same note (the Generate Video page renders from it).
2. Rename. The remaining veo3 / Veo3 mentions in ai-and-imports.mdx, mcp/tools.mdx and openapi.json (request example, type enum, images description) become seedance / Seedance 2.0 (Audio + Video), matching the identifier and title the app has used since the EvoLink migration. The documented parameters (prompt, optional images up to 3) already match the Seedance DTO and were left as is.

cloud/trial.mdx already describes the restriction generically and was not changed; cloud/limits.mdx needs nothing. No veo3 or kie.ai mention remains in the repo.

Why was this change needed?

A Cloud customer on the trial hit the 406 finish-trial dialog when trying to generate a video and complained that nothing had said the generator was paid-only. gitroomhq/postiz-app#2062 adds that disclosure in the app; this PR adds it to the docs and cleans up the stale Veo3 naming at the same time.

QA

1. Run npx mint dev and open /general/composer/ai-and-imports: the AI video list names Seedance 2.0 (Audio + Video) with the paid-plans and trial sentence linking to /cloud/trial, and Image and text slides says it works during the trial
2. Open /cloud/plans: the credits paragraph mentions that only trial-available generators (currently Image Text Slides) work during the trial, with a working /cloud/trial link
3. Open /mcp/tools#generatevideooptions: the type example reads seedance and the table row reads Seedance 2.0; under generateVideoTool the 406 sentence is present
4. Open /public-api/video/generate: the request example is titled Seedance 2.0 (Audio + Video) with "type": "seedance", the type enum offers seedance, and a 406 response is listed
5. public-api/openapi.json still parses as JSON, and grep -ri veo3 over the repo (excluding node_modules) returns nothing

📝 Walkthrough

Walkthrough

The documentation replaces Veo3 with Seedance 2.0 for video generation. It documents trial-plan restrictions, the 406 response for unavailable generators, trial-supported Image Text Slides, and monthly credit behavior.

Changes

Video generation documentation

Layer / File(s)	Summary
OpenAPI video generation contract public-api/openapi.json	The video generation example and VideoGenerationRequest.type enum now use seedance. The specification documents Seedance 2.0 and the 406 trial-plan response.
Product and MCP documentation cloud/plans.mdx, general/composer/ai-and-imports.mdx, mcp/tools.mdx	The documentation identifies Seedance 2.0 as the prompt-driven video generator, describes trial availability, updates MCP examples, and clarifies credit behavior.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to d4d87

This updates the documented video generator and trial response contract. Merge after the related application deployment so users and API clients do not receive instructions for behavior that is not yet available.
