Describe what the PR does:

Adds recognition for the SimpliSafe Smart Alarm Wireless Indoor Camera, which the API reports as camera model scout and as sensor device type 21.

• CameraTypes.SCOUT_CAMERA, mapped from model "scout" in MODEL_TO_TYPE
• DeviceTypes.SCOUT_CAMERA = 21

Before this change, a system with one of these cameras logs Unknown camera type: scout and Unknown device type: 21 on load (seen in Home Assistant 2026.11 with simplisafe-python 2026.09.0). I checked a captured API response from my own V3 system: the subscription's camera list has an entry with "model": "scout", and the sensors list has a "type": 21 entry whose serial matches that camera's serial (the last 8 characters of its uuid). So type 21 is the same physical camera showing up in the sensors list.

This only maps the types. It does not add live view or video support for scout. These cameras report webRTCProvider: kvs, and I have not tested video_url() against one.

Does this fix a specific issue?

Fixes #1186

Checklist:

• Confirm that one or more new tests are written for the new functionality.
• Run tests and ensure everything passes (with 100% test coverage).
• Update README.md with any new documentation. (Not needed, the docs don't list camera types.)

Tests: new test_scout_camera loads a V3 system with a scout camera added to the subscription and sensor fixtures, checks the camera type and sensor type, and asserts nothing is logged as unknown. test_device_type_21 checks the raw mapping. Fixtures are built from a real capture with identifiers zeroed or redacted. Full suite passes at 100% coverage; ruff and mypy are clean.
