Refactors the event layout and stacking logic based on review feedback.
This includes:
- Merging conflicting event groups to prevent inconsistencies.
- Implementing minimal stack level assignment using a min-heap.
- Consolidating styling and using DateService for drag operations.
- Adding reflow after drag and drop.
- Improving the column event filtering to include events overlapping midnight.
- Ensuring explicit sorting of events for grid layout.
Refines the event grid layout algorithm to more accurately
identify conflicting events for stacking within the grid.
Now uses an expanding search to find chains of conflicting events,
ensuring that all events that should be grouped together are
correctly identified.
Introduces a coordinator to manage event layout calculations,
separating this logic from rendering.
It calculates stack levels and allocates event columns for
improved visual organization of calendar events.
Enhances date validation and timezone handling using DateService, ensuring data integrity and consistency.
Refactors event rendering and dragging to correctly handle date transformations.
Adds a test plan for event stacking and z-index management.
Fixes edge cases in navigation and date calculations for week/year boundaries and DST transitions.
