Subject: [PATCH] feat: add 'No Webcam' layout preset to hide webcam in final
 recording

Adds a new 'No Webcam' option to the webcam layout preset dropdown in the editor. When selected, the webcam feed is completely hidden from both the preview and the exported video, allowing users who recorded with a webcam to exclude it from the final output.

- Add 'no-webcam' to WebcamLayoutPreset type union and preset map

- Handle 'no-webcam' in computeCompositeLayout (returns webcamRect: null)

- Add 'no-webcam' case in project persistence normalization

- Add 'No Webcam' option to the layout preset dropdown in SettingsPanel

- Add 'noWebcam' i18n translation key (en)
