fix(web): resolve ESLint regressions from eslint-config-next upgrade
- Escape unescaped entities (react/no-unescaped-entities) in step-remote,
step-welcome, projects-view, settings-panels
- Add targeted eslint-disable-next-line for react-hooks/set-state-in-effect
on established async-fetch and prop-sync patterns in useEffect bodies:
chat-mode, file-content-viewer, files-view, step-dev-root, projects-view,
settings-panels, update-banner, visualizer-view, carousel, use-mobile
- Add targeted eslint-disable-next-line for react-hooks/purity on Date.now()
display timestamps in streaming chat messages (chat-mode)
- Remove now-unused eslint-disable directives (projects-view, settings-panels)
