Form fields in mobile view of taxonomy screens use inconsistent width

[sainathpoojary]

In the mobile view of taxonomy screens (e.g. Posts > Categories, Posts > Tags), the form fields in the “Add New” section are styled with width: 95%, which results in a narrower appearance compared to:

• The search input at the top
• The taxonomy table below

This creates a subtle but noticeable inconsistency in layout and visual rhythm.

Steps to reproduce:

1. Open the WordPress admin on a mobile device or use responsive mode in browser dev tools.
2. Navigate to Posts > Categories or Posts > Tags.
3. Observe the “Add New” form fields.
4. Notice that the fields are narrower (95%) compared to the full-width elements above and below.

Environment

• WordPress: 6.9-alpha-60093-src
• PHP: 8.2.28
• Server: nginx/1.27.5
• Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
• Browser: Chrome 135.0.0.0
• OS: macOS
• Theme: Twenty Twenty-Five 1.2
• MU Plugins: None activated
• Plugins: Test Reports 1.2.0

Screenshots

This PR improves visual consistency in the mobile view of taxonomy screens (e.g., Categories, Tags) by updating form field widths in the “Add New” section. Inputs, textareas, and selects now use width: 100% instead of 95%, aligning them with the search input and table layout.
