fix(FN-758): fix project-scoped real-time dashboard updates

- Add project-store-resolver to correctly scope SSE and WebSocket connections to the active project's TaskStore
- Fix shared resolver so multi-project setups deliver task events only to the right dashboard clients
- Add regression tests for project store resolver (routing, missing project, SSE integration)
- Remove unused import and clean up stale changeset
- Add changeset for published package patch bump
