chore: bulk dependency updates + fix immer v11 default import + sentry test

Package updates (safe minor/major bumps, all build-verified):
- @tanstack/react-query 5.24->5.100, react-virtual 3.2->3.13
- jotai 2.6->2.20, immer 9->11, dayjs, chroma-js, classnames, blurhash
- slate/slate-dom/slate-react 0.123->0.124
- focus-trap-react 10->12, react-error-boundary 4->6
- html-dom-parser 4->7, html-react-parser 4->6
- pdfjs-dist 4->5, ua-parser-js 1->2
- i18next-http-backend 3->4, i18next-browser-languagedetector 8.0->8.2
- react-aria 3.29->3.48, matrix-widget-api 1.16->1.17
- @atlaskit/pragmatic-drag-and-drop* minor bumps
- @rollup/plugin-inject 5.0.3->5.0.5, @rollup/plugin-wasm 6.1->6.2
- @element-hq/element-call-embedded 0.19.3->0.19.4
- @types/* patches, eslint-plugin-* minors

Breaking change fix:
- immer v11 removed default export; updated 11 files to named import

Temporary: add Sentry test button to WelcomePage for verification.
Remove after confirming errors reach the dashboard.
