## Summary by CodeRabbit

* **New Features**
* Integrations panel in Account Settings to link/unlink calendar
providers.
  * Collapsible settings wrapper for improved layout.

* **Improvements**
* Calendar system reworked: per-account calendar groups, simplified
toggles with explicit Save, richer event display (multi-dot date
indicators), improved event time/title handling across journal views.

* **Localization**
* Added calendar keys: save-error, no-journal, no-calendar; removed
legacy duplicate-error keys.
