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

For input type number width it not look good normal state but when hover over the changes make sense.

Suggested change

	.wp-core-ui .date-time-fields .day-fields.clear select,
	.wp-core-ui .date-time-fields .time-fields.clear select {
	.customize-control-date_time select {

This only needs a class and an element to override .wp-core-ui select { vertical-align: middle; } in forms.css. The .customize-control-date_time class would cover both the date and the time.

[sabernhardt]

Instead of adding another 5 or 6 pixels to each input's width, you could add the tiny-text class on each of these number fields. The forms.css stylesheet already removes the right padding to make room for the increment/decrement buttons.

(small-text might seem more appropriate for the Year field, but it still has padding on small screens and the Customizer's width works with tiny-text)

[mukeshpanchal27]

I like the idea to add the class and apply CSS their.
