SnapOtter 8532f3227b docs: audit all 157 tool pages against live schemas

Reconcile every tool page's parameters, defaults, and response shape against the tool's Zod settings schema and executionHint in code. Notable fixes: color-palette (add count + format params, hex output, median-cut algorithm), favicon (add 5 params, was documented as having none), qr-generate (add logoDataUri), convert (add ppm/eps/tga formats), video-loudnorm (-16 LUFS not -14), smart-crop (async 202 not sync 200), images-to-video (1080x1080 square), and several output-filename and behavior-note corrections.

Also normalize API endpoint paths to /api/v1/tools/<id> (no modality segment) and standardize curl examples on the Docker API port 1349. Verified with a clean docs build.

Example Request

curl -X POST http://localhost:1349/api/v1/tools/watermark-pdf \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@document.pdf" \
  -F 'settings={"text": "CONFIDENTIAL", "position": "c", "opacity": 0.2, "rotation": 45}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",

  "originalSize": 2450000,
  "processedSize": 2500000
}

Notes

The watermark is rendered as a text overlay on each page.
The same watermark text, position, and style are applied uniformly to all pages.
Use lower opacity values (0.1-0.3) for subtle watermarks that do not obscure content.
