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.

Parameters

Parameter	Type	Required	Default	Description
format	string	No	`"mp3"`	Output format: `mp3`, `wav`, `ogg`, `flac`, `m4a`

Example Request

curl -X POST http://localhost:1349/api/v1/tools/convert-audio \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@audio.mp3" \
  -F 'settings={"format": "flac", "bitrateKbps": 256}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.flac",

}

Notes

Supported input formats include MP3, WAV, OGG, FLAC, AAC, M4A, WMA, AIFF, and OPUS.
Bitrate only applies to lossy formats (MP3, OGG, M4A). Lossless formats like WAV and FLAC ignore this setting.
The output filename keeps the original name with the new extension.
