refactor: rename all secret scanner internals to auto-redact

Full internal rename since still in testing — no backwards compat needed:
- secret-scanner.js → auto-redact.js
- SecretScanner → AutoRedact
- SECRET_PATTERNS → REDACT_PATTERNS
- secretScanning → autoRedact (setting key)
- customSecretPatterns → customRedactPatterns (setting key)
- scanAndRedactSecrets → runAutoRedact (function)
- All DOM ids, CSS classes, and variable names updated
- category: 'secret' → category: 'redact'
- getOrgSecretPatterns → getOrgRedactPatterns
