Describe this PR

• Previous integration of hotosm/ui worked for dev frontend, but builds were failing.
• Updated to React v19, required to support native web components.
• Updated all other dependencies, replacing many deprecations in tanstack-query and redux/toolkit.
• Fix to custom type declarations, including for hotosm/ui.
• Correctly import hotosm/ui from js files.
• See all other updates in commit messages.

Apologies for the broken build from the previous PR!
Please review and test this thoroughly @suzit-10 🙏

Possible issues:

• @react-spring/web was the only dependency that doesn't officially support React 19 I think.
• The devs are a few days / weeks away from providing official support...
• Extra attention should be paid to testing Tutorial/index.tsx.
• If it doesn't work as intended, is it possible to replace the lib? Else we just wait a bit for the official support...
