Benchmark PR TryGhost#25189

Type: Clean (correct implementation)

Original PR Title: Updated activitypub Bluesky sharing enablement flow
Original PR Description: ref TryGhost/ActivityPub#1377

We updated the backend implementation of the Bluesky sharing enablement process to include a confirmation step in which the client would prompt the backend to check what handle has been assigned to the Bluesky account generated by Bridgy Fed - This circumvents the need to for us to compute the handle manually and potentially getting it wrong if we compute it in a different way to Bridgy Fed

Note

Switch Bluesky sharing to v2 enable/disable endpoints, add handle confirmation flow with polling, update UI/state, and bump package to 2.0.0.

• API:
  • Migrate Bluesky endpoints to v2 (enable, disable) and add confirm-handle endpoint.
  • Change enableBluesky() to no longer return a handle; introduce confirmBlueskyHandle() returning a confirmed handle or empty string.
  • Extend Account with blueskyHandleConfirmed and make blueskyHandle nullable.
• Hooks (apps/activitypub/src/hooks/use-activity-pub-queries.ts):
  • Add useConfirmBlueskyHandleMutationForUser and cache updater for Bluesky details.
  • Update enable/disable mutations to set {blueskyEnabled, blueskyHandleConfirmed, blueskyHandle} appropriately and invalidate follows.
• UI (views/Preferences/components/BlueskySharing.tsx):
  • Implement enablement confirmation flow with polling, loading states, success/error toasts, and conditional rendering once handle is confirmed.
  • Update disable flow and button states; show link to Bluesky profile when confirmed.
• Tests (src/api/activitypub.test.ts):
  • Update Bluesky tests for v2 endpoints; add tests for handle confirmation and null/invalid responses.
• Package:
  • Bump @tryghost/activitypub version to 2.0.0.
