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 owncloud/reva#432 to be merged in Reva.
This PR depends on this PR owncloud/ocis#11758 to be merged in oCIS.

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
• Self-Domain Prevention: Prevent users from selecting their own instance
• 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
