feat(ocm): implement WAYF page and enhance invitation workflow

[MahdiBaghbani]

Although this PR is referenced under cs3org/OCM-STA#1, it is not directly part of the STA funded work. However, since the changes are closely related and beneficial to OCM, I decided to port them here as well for consistency.

This PR depends on this PR opencloud-eu/reva#393 to be merged in Reva.
This PR depends on this PR opencloud-eu/opencloud#1714 to be merged in OpenCloud.

Description

This PR implements the frontend components for WAYF (Where Are You From) functionality in the OCM web application, enabling users to discover and select their cloud provider when accepting federated invitations. The implementation provides a user friendly interface for OCM provider selection and complements the backend WAYF discovery endpoints.

Technical

Things I've added to the web application:

• WAYF Page: Provider selection interface with federation browsing and manual provider entry
• WAYF is public page: Public access to WAYF page without authentication requirement
• Invitation Acceptance Modal: Component for invitation acceptance workflow from other EFSS WAYF Pages
• Token Management: Multiple copy formats (plain, base64, WAYF link) for outgoing invitations
• Shared Composables: Reusable logic for invitation acceptance and WAYF functionality
• Federation list display with automatic grouping
• Manual provider domain entry with OCM discovery

Code Changes

• New Components:

  • src/views/Wayf.vue: Main WAYF page with provider selection UI, search functionality, and federation display
  • src/views/InvitationAcceptanceModal.vue: Modal component for accepting invitations with provider validation

• New Composables:

  • src/composables/useWayf.ts: Core WAYF logic including federation loading, provider discovery, and self-domain validation
  • src/composables/useInvitationAcceptance.ts: Shared invitation acceptance logic with self-generated token detection

• New Types:

  • src/types/wayf.ts: TypeScript interfaces for federation and provider data structures

• Updated Routing (src/index.ts):

  • Added /wayf route with authContext: 'anonymous' for public access
  • Added /accept-invite route for invitation acceptance workflow
  • Included authentication context documentation

• Modified Views:

  • src/views/OutgoingInvitations.vue: Added three token copy options (plain, base64, WAYF link) with visual improvements
  • src/views/IncomingInvitations.vue: Refactored to use shared useInvitationAcceptance composable
  • src/views/ConnectionsPanel.vue: Minor UI adjustments
  • src/views/App.vue: Updated to support new routes

• Documentation:

  • docs/Where Are You From page.md: WAYF usage guide, API endpoints, and testing scenarios

Since the backend PRs are merged by now we'll start reviewing the web part (this PR) next

Hey @MahdiBaghbani thank you for this contribution! Looked at it today, together with @JammingBen and it looks good so far. We have some ideas for improvements but would do those as a followup to your PR (using vue-concurrency for loading and error states on requests, pushing modals to the modals store, etc - nothing you need to dig into ;-) ). We're struggling to get this running on local dev machines, because self signed certificates seem to be an issue in server-to-server OCM communication on the discover endpoint.

Do you have any hints for us how to get this running with self signed certs? 🙈
