Modernize Schedule PTO form with enhanced styling and user guidance

Improves the Schedule PTO form section with modern design elements:

Design enhancements:
- Add left border accent in primary color to highlight the card
- Add gradient background to header with descriptive subtitle
- Include icons next to each form label (tag, chat, calendar)
- Upgrade all form controls to large size for better touch targets
- Add helpful placeholder text with examples (e.g., "Summer Vacation")
- Include descriptive helper text below fields for guidance
- Make submit button full-width and large for prominence
- Add tip box at bottom with success border highlighting post-submission info
- Increase padding and spacing (mb-4) for better breathing room

The form now feels more guided, professional, and easier to use.
