Refine inline URL editor event handling

- Add double-checks in global click handlers to prevent race conditions
- Add isCurrentlyMounted flag to prevent cleanup during re-renders
- Remove onBlur handler that was causing premature editor closure
- Simplify conditional logic in click handlers

These changes improve the robustness of the inline editor when
websocket updates occur during editing sessions.
