Task 1: Fix UAT-001 - Multiple category parameters causing 400 error src/app/api/providers/fal/models/route.ts, src/lib/providers/fal.ts Fix the fal.ai API route to handle multiple categories correctly.

Root cause: The buildCategoryFilter() function creates category=text-to-image&category=image-to-image&... but fal.ai API only accepts a single category parameter.

Fix approach: Fetch all models without category filter and filter client-side.

1. In route.ts:

   • Remove buildCategoryFilter() function entirely
   • Remove category params from URL construction (line 130)
   • Keep only status=active in base URL
   • Rely on existing isRelevantModel() filter (line 172) to filter results

2. In fal.ts (provider):

   • Apply same fix to listModels() and searchModels() functions
   • Remove any category URL params, filter results after fetch

Why this approach:

• Simpler than making 4 parallel API calls per category
• fal.ai returns manageable number of models
• Filtering is already implemented via isRelevantModel()
• No additional latency from multiple requests curl -X GET "http://localhost:3000/api/providers/fal/models" returns JSON with success:true and models array
• API route returns 200 with models array
• Models are filtered to only image/video categories
• No 400 errors from fal.ai

Before declaring plan complete: - [ ] `curl http://localhost:3000/api/providers/fal/models` returns success:true - [ ] Response contains models with capabilities: text-to-image, image-to-image, text-to-video, image-to-video - [ ] No models with other categories (audio, 3D, etc.) in response - [ ] TypeScript compiles: `npx tsc --noEmit` - [ ] Build succeeds: `npm run build`

<success_criteria>

• UAT-001 resolved - API route returns models without 400 error
• Models still filtered to relevant image/video categories
• No regression in other functionality </success_criteria>
