* Changes from fix/event-hook-endpoint
* fix: Allow empty eventHooks/ntfyEndpoints to reconcile from server
Remove the `length > 0` guards in fast-hydrate reconciliation that
prevented intentional empty-array clears from syncing across clients.
Server-side wipe protection (`__allowEmpty*` escape hatches) already
ensures empty arrays in the server are intentional.
Addresses PR #831 review feedback from CodeRabbit and Gemini.
