Goal

Reduce React console/runtime errors reported in browser logs, prioritizing crash-level issues.

Identify source components from stack traces
Fix crash-level runtime errors (Select is not defined, invalid React DOM usage)
Fix high-noise compatibility warnings in touched components (selected on <option>, objectName prop, legacy lifecycle names, cellspacing/cellpadding)
Run targeted checks and summarize remaining warnings
Prevent browser-mode crash when video store calls native-only jamClient capture-resolution APIs
Reduce additional high-noise UI warnings (bind(this) in render, JamClassScreen legacy lifecycle, missing row keys)

Patched JamTrackAutoComplete to gracefully fall back when Select is unavailable.
Fixed TeacherExperienceEditableList unmount lifecycle typo and invalid input markup.
Updated WebcamViewer to use controlled <select> values instead of selected on <option>.
Added ReactRailsUJS.findOrCreateRoot compatibility override in react-init.js to avoid repeated createRoot warning path.
Did a targeted static validation via rg/git diff review; full browser/runtime test pass still needed.
Addressed browser/client-mode regression context.jamClient.FTUEGetCaptureResolution is not a function in VideoStore.onRefresh.
Added missing capture-resolution API stubs to fakeJamClient.js (FTUEGetCaptureResolution, FTUEGetCurrentCaptureResolution, FTUESetCaptureResolution) and wired exports.
Hardened VideoStore and webcam_viewer to guard optional capture-resolution APIs and degrade gracefully when unavailable.
Removed render-time .bind(this) usage in ChatWindow, FindSessionOpen, and SessionFilesBtn to suppress create-react-class autobind warnings.
Renamed JamClassScreen.componentWillUpdate to UNSAFE_componentWillUpdate.
Added explicit key props for static onboarding rows in AccountOnboarderScreen.
