fix(web): silence svelte 5 warnings, add missing enrichment proxy

- Wrap $state initializers that read props (MarketForm, ResearchPanel,
  maerkte +page) in untrack() so Svelte 5 stops warning about
  state_referenced_locally. Intent stays "take an initial snapshot of
  the prop" — the warning existed to make that intent explicit.
- Add enrichment/crawl-all-status/+server.ts proxy route; the admin
  discovery page was polling this path and getting 404s in a tight
  loop because the equivalent SvelteKit proxy only existed for the
  plain /crawl-status endpoint.
