[BUG]: Make copyright year dynamic in About page footer

### Bug Description

The About page footer currently uses a hard-coded copyright year, which requires manual updates every year. This can lead to outdated information if not updated on time.
To improve maintainability, the year should be generated dynamically using JavaScript so it always reflects the current year automatically.
