Document screen and webcam recording

[JackWilb]

Why

Document the screen and webcam recording support added to the ReVISit study application so study designers can configure capture, permission pages, analysis replay, and downloads.

Related implementation: revisit-studies/study#1159.

Architecture

The guide documents the existing configuration flags and permission components for screen-only, webcam-only, and combined recording. It explains that screen and webcam are stored as separate assets, while analysis and downloads expose them through the shared recording controls.

User-facing impact

• Study designers can find setup examples for recordScreen, recordWebcam, and the two permission components.
• The analysis replay layouts are documented: side by side, picture in picture, and webcam on top.
• The data-export page explains bulk and task-level downloads for screen, webcam, or both.
• The known limitation for recording requirements introduced only inside a dynamic block is documented, with the recommended configuration workaround.
• Existing screen-recording pages were updated; no separate webcam documentation page was added.

Validation

• corepack yarn build passed.
• git diff --check passed.
• corepack yarn checkLinks scanned 2,951 links and found one unrelated pre-existing 404 in the adoption page: https://buggenhoudt.pages.lisn.upsaclay.fr/revisit2/metroflow-test/.

Risk and rollout

Documentation-only change. No application behavior or versioned documentation was changed. Typedoc remains release-generated as documented in the repository instructions.
