Takes src/lerobot/cameras/ to 100% public docstring coverage, the first module of Wave 1 after Person A's
robots/ pilot and infrastructure PR. Converts the three config classes that already had prose but used a
bold **Attributes**: block (invisible to check_docstrings.py, not the standard's Args: pattern for config
dataclasses) and documents the previously-bare CameraConfig, its three enums, ZMQCameraConfig, and the
module's utility functions. Adds per-backend sections to docs/source/api/cameras.mdx and removes the
module's ruff D-ignore.
