Improves all-day event row height calculation

Ensures consistent all-day event row height calculation across CSS and TypeScript.

The all-day event row height calculation is adjusted by removing redundant container padding from the TypeScript constant and synchronizing the CSS variable with the event height.

Additionally, the layout engine is directly tested in the test file for better coverage.
