Fix NVDA double label announcement in Table Designer input fields

[Copilot]

Summary

Fixes issue where NVDA screen reader announces label names twice for input fields and text areas throughout the Table Designer, causing poor accessibility for screen reader users.

Problem

Screen reader users experience cognitive overload and confusion due to redundant label announcements. For example, when focusing on a column name input field, NVDA would announce:

• "Column Name, Column Name, edit text"

This behavior was consistent across all input fields and text areas in the Table Designer, significantly impacting the user experience for users relying on auditory feedback.

Root Cause

The designerInputBox.tsx component was creating duplicate ARIA label associations:

1. Fluent UI's Field component with a label prop automatically associates the label with its child input elements through proper ARIA attributes
2. Explicit aria-labelledby attributes were manually added to both Input and Textarea components, referencing a generated ID

This double association caused screen readers to announce the label twice—once from the Field's automatic handling and once from the explicit aria-labelledby attribute.

Solution

Removed redundant aria-labelledby attributes from Input and Textarea components in designerInputBox.tsx. The Fluent UI Field component already handles accessibility associations correctly through its internal implementation, making the explicit attributes unnecessary and harmful.

Changes:

• Removed useId import (no longer needed)
• Removed dropdownId variable declaration
• Removed aria-labelledby attribute from Input component
• Removed aria-labelledby attribute from Textarea component

Impact

• ✅ Screen readers now announce each label only once
• ✅ Complies with WCAG 1.3.1 (Info and Relationships) accessibility standards
• ✅ No breaking changes to existing functionality
• ✅ Verified no similar issues exist elsewhere in the codebase

Testing

• Linting: ✅ Passed
• Build: ✅ Succeeded
• Packaging: ✅ VSIX created successfully (12.75 MB)

Environment Details:

Application: MSSQL for VSCode.
Visual studio code version: 1.102.1
OS: Windows 11 Enterprise 24H2
Build: 26100.4652
Screen reader
NVDA Version: 2024.4.1

Repro Steps:

1. Launch visual studio code application
2. Sign in with "GitHub" account
3. Tab till "Extension" and press enter
4. Tab till search box and enter "SQL" (mssql) server and install extension
5. Tab till any database and click on "edit"or "add" and press enter
6. New table screen will get open .
7. Tab till "Column" tab and press enter.
8. Observe that NVDA is unnecessarily announcing label name twice throughout the application

Actual:

NVDA announces the label name twice for various controls throughout the application. This behavior is consistent across multiple screens and components, leading to repetitive and potentially confusing output.
Note: Issue is observed in throughout the application

Expected:

Screen readers like NVDA should announce each label once, clearly and concisely, when focus lands on a control. This ensures users receive accurate and non-redundant information.

User Impact:

Screen reader users may experience cognitive overload or confusion due to redundant announcements. This can slow down navigation, reduce efficiency, and impair the overall user experience—especially for users relying on auditory feedback for form completion
