Update JS dependencies and misc tweaks (#37064)

- Update all JS deps
- Regenerate SVGs
- Add new eslint rules from unicorn
- Update typescript config for 6.0, remove deprecated options in favor
of `strict` with disablements, remove implicit dom libs.
- Set vite log level during `watch-frontend` to `warn` to avoid
confusing URLs or HMR spam from the dev server to keep the log concise.
Overridable via `FRONTEND_DEV_LOG_LEVEL`.
