[AbhishekPAnil]

Summary

Adds support for copying and downloading event JSON-LD structured data for embedding on external sites.

Changes

• Added StructuredDataModal with:

  • JSON-LD preview
  • Toggle to wrap JSON-LD in a <script> tag
  • Copy to clipboard
  • .jsonld file download

• Added getEventStructuredData service to fetch event structured data via:
  GET /events/{id}?include-json-ld=true

• Updated Event List and read-only Event View to expose:

  • Get structured data
  • Copy JSON-LD

• Refactored EventStatus dropdown to use inline writeTier instead of ProtectedComponents.

  • Read actions are always visible.
  • Write actions remain RBAC-gated.

• Added EN/FR i18n keys for structured data functionality.

• Added VITE_APP_OPEN_API_URL to the staging environment configuration.

As far as I can see, the structured-data PR is first causing repeated TC03 failures because the addition of “Get structured data” before the Edit button exposes a brittle RT selector (the exact kind of issues I am working on to eradicate, adding data-cy in the remaining 10% of the app). Cypress currently targets Edit using .outlined-label; both controls are outlined buttons, so Cypress now clicks “Get structured data” instead of Edit. I'll add/use a semantic hook with data-cy="button-edit-event", and you can add data-cy="button-get-structured-data-event" in this PR.
