Redmine

The current calendar view highlights the current day using a yellow background color.
However, this color is very similar to the background used for issue entries, making it difficult to visually distinguish the "today" indicator from issue highlights.

This patch improves the calendar layout by changing the today marker from a yellow background to a blue circular indicator surrounding the date number.
As a result, the current day becomes clearer and easier to recognize without conflicting with the issue background styling.
The blue circle is the same color as the existing badge.
