Device-picker modal for camera/mic selection and mobile camera flipping.

• Builds dropdowns from parameters.videoInputs and parameters.audioInputs (list of MediaDeviceInfo from flutter_webrtc).
• Current selection defaults to userDefaultVideoInputDevice and userDefaultAudioInputDevice.
• Dropdown changes invoke switchVideoOnPress or switchAudioOnPress, which call switchVideo/switchAudio to update tracks, then persist new deviceId to userDefaultVideoInputDevice/userDefaultAudioInputDevice.
• "Switch Camera" button (mobile-only) calls switchCameraOnPress (defaults to switchVideoAlt), toggling front/back cameras.
• Positions via getModalPosition using options.position.
• Offers seven builder hooks (wrapperBuilder, containerBuilder, headerBuilder, sectionBuilder, dropdownBuilder, buttonBuilder) plus customBuilder for full replacement, enabling custom device previews, permission prompts, or QR-based device linking.

Override via MediasfuUICustomOverrides.mediaSettingsModal to inject live preview tiles, device aliases, or permission checks.
