Enhances event rendering and grid updates

Improves event rendering by adding styling, filtering out all-day events (handled by GridManager), and calculating accurate positioning within the time grid.

Optimizes grid updates to avoid unnecessary rebuilding, instead updating only the week header for all-day events, leading to better performance.
