Refactors all-day event rendering to use a layout engine
for overlap detection and positioning, ensuring events
are placed in available rows and columns.
Removes deprecated method and adds unit tests.
Removes the `swp-allday-event` custom element, using `swp-event` for all-day events instead. All-day events are now distinguished by their parent `swp-allday-container`. Simplifies element management and CSS selectors.
Centralizes drag event listener setup in `EventRendererManager` for better separation of concerns.
Introduces factory and cloning methods in `SwpEventElement` to simplify event cloning and data extraction from DOM elements during drag operations.
Enhances `DragDropManager` to pass the actual dragged element for conversion and accurately detect the drop target (day column or header).
Updates `EventRenderer` to expose drag-handling methods publicly, allowing the `EventRendererManager` to delegate event-specific drag operations based on drop target.
Addresses two key issues related to dragging events to the header: the premature removal of the original event element and the creation of duplicate all-day events.
The original event is no longer removed when dragging to the header; it is now only removed upon a successful drop.
Also, it prevents the creation of duplicate all-day events by checking for existing all-day events before creating new ones, using DOM queries to ensure accurate state.
Ensures that all-day events are placed in the first available row within their column to avoid overlapping.
It achieves this by querying existing all-day events, determining occupied rows based on their grid-row-start style, and then assigning the new event to the next available row.
Centralizes event position calculations into `PositionUtils` for consistency and reusability across managers and renderers.
Improves drag-and-drop functionality by emitting events for all-day event conversion and streamlining position calculations during drag operations.
Introduces `AllDayManager` and `AllDayEventRenderer` to manage and render all-day events in the calendar header. This allows dragging events to the header to convert them to all-day events.
Addresses inconsistent time formatting and lack of timezone
handling throughout the application by introducing a
`TimeFormatter` utility.
This class centralizes time formatting logic, providing
timezone conversion (defaults to Europe/Copenhagen) and
support for both 12-hour and 24-hour formats, configurable
via `CalendarConfig`.
It also updates event rendering to utilize the new
`TimeFormatter` for consistent time displays.
Introduces the ability to convert all-day events to timed events by dragging them out of the header.
Leverages a factory method to create timed events from all-day elements, ensuring proper data conversion and styling.
Improves user experience by allowing more flexible event scheduling.
Creates `SwpEventElement` and `SwpAllDayEventElement` classes for handling event rendering.
Refactors event creation logic in `EventRenderer` to utilize these classes, improving code organization and reusability.
Adds factory methods for creating event elements from `CalendarEvent` objects, simplifying event instantiation and data management.
