FN-6208: sync workflow settings across nodes

Synchronize workflow setting values through node settings sync.

- Include workflow settings in settings payloads, diffs, status responses, and API types.
- Apply inbound and pulled workflow settings through the TaskStore while ignoring rejected setting ids.
- Add core, route, hook, API, and Nodes view coverage for workflow settings sync behavior.
- Add a patch changeset for the published Fusion package.
