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.

# Unlock PDF
Remove password protection from an encrypted PDF by providing the correct password.
## API Endpoint
`POST /api/v1/tools/unlock-pdf`
Accepts multipart form data with a PDF file and a JSON `settings` field.
## Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| password | string | Yes | - | Password to decrypt the PDF (1-256 characters) |
## Example Request
```bash
curl -X POST http://localhost:1349/api/v1/tools/unlock-pdf \
-H "Authorization: Bearer si_your-api-key" \
-F "file=@document.pdf" \
-F 'settings={"password": "s3cret"}'
```
## Example Response
```json
{
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/document.pdf",
"originalSize": 2500000,
"processedSize": 2450000

- Either the user password or the owner password will work for decryption.
- Passwords are redacted from audit logs.
