Highlight current date when selecting another date in the calendar

[nikhilmaurya-21]

When using the calendar component, I noticed that the current date becomes visually indistinguishable when another date is selected. It would be helpful if the current date was highlighted or styled differently, even when a different date is chosen, to provide a clear indication of today's date.

Expected Behavior:

• The current date should have a distinct style (e.g., different color, border, or background) that persists, regardless of whether another date is selected.
• When the user selects another date, the selected date should still be highlighted, but the current date should remain visually distinct from other dates.

Steps to Reproduce:

1. Open the calendar.
2. Select any date other than the current date.
3. Observe that the current date is no longer visually highlighted, making it difficult to identify.

Proposed Solution:

• Add a distinct style (such as a different color or border) for the current date, which remains visible even when another date is selected.
• Ensure that the selected date and the current date have separate visual indicators to avoid confusion.
