Bohdan Triapitsyn b09614fd68 refactor(quota): secure managed provider credentials (#2160)
- add shared owner-only credential storage for OpenCode Go, Ollama Cloud, and Cursor
- validate credentials before atomic writes using 0700 directories and 0600 files
- replace provider-specific credential routes with an allowlisted lifecycle API
- stop automatically reading Ollama's legacy cookie file
- stop reading or modifying Cursor's database during regular quota requests
- add explicit one-time Cursor credential import without mutating Cursor storage
- persist refreshed Cursor credentials only in OpenChamber-managed storage
- add Ollama Cloud and Cursor credential controls to provider settings
- preserve OpenCode Go tracking through the shared credential flow
- add VS Code credential management and Cursor quota parity
- reject authentication redirects, enforce request timeouts, and fail on unparseable usage pages
- mask stored secrets in API responses and extend quota security coverage
- update quota provider documentation
