Update webcam streams to use davidia server

Currently, some mjpg streams have multiple issues:
- mjpg streams are often using `http`, rather than `https`, causing issues for authenticated clients
- some mjpg streams are unavailable outside the beamline network

When available, we should update camera streams to use a davidia server or other equivalent technique for viewing.

Start by locating the camera and MJPG stream configuration in the TypeScript monorepo and identify streams using HTTP or restricted to the beamline network. Done means affected streams use a davidia server or equivalent, use HTTPS, and are viewable by authenticated clients outside the beamline network.
