feat(cells): Remove legacy non-org-scoped accept invite API route

The /api/0/accept-invite/{member_id}/{token}/ endpoint required no organization
context, relying on a cell mapping lookup to determine the org. The org-scoped
/api/0/accept-invite/{organization_id_or_slug}/{member_id}/{token}/ is now the
only supported cell-safe route.

This PR removes the legacy API route and any references to it:
- Remove the URL pattern from api/urls.py
- Remove the legacy pattern from controlsiloUrlPatterns.ts (regenerated)
- Remove the legacy type from knownSentryApiUrls.generated.ts (regenerated)
- Remove entries from the apidocs ownership and publish status allowlists

Removing this route is harmless as the web UI has been updated to always use the
new url in #112634. This is not a public
URL that requires a formal deprecation process.
