Customizer: Fix input field widths and alignment for date-time controls

[Infinite-Null]

Trac ticket: #51249

What

• Increased the width of date-time input fields from 46px to 52px
• Added vertical alignment to select fields in day and time controls

Why

• The previous width of 46px was causing text to be truncated
• Select fields were misaligned with neighboring elements, creating visual inconsistency

How

• Updated width property in date-time input styles to accommodate longer text
• Added vertical align: top to select elements within day and time field groups

Testing Instructions

1. Go to Customizer
2. Navigate to any panel with date-time controls
3. Verify date/time input fields show complete numbers without truncation
4. Check that select fields are properly aligned with neighboring inputs
