Motivation

Users reported that the "display a copy button" option was missing for fields in MariaDB connections. The issue occurred because the text-copy plugin only registered copy button settings for Input fields, but MariaDB and other databases often use different field types like Input.TextArea, Input.URL, Input.JSON, etc. This limited the copy functionality to only basic input fields.

Description

Key changes:

• Extended the text-copy plugin to support 8 text-based field types instead of just Input
• Created a reusable addCopyButtonSetting function to reduce code duplication
• Added support for: Input.TextArea, Input.URL, Input.JSON, InputNumber, Markdown, MarkdownVditor, RichText
• Maintained backward compatibility with existing Input field functionality

Potential risks:

• Low risk. The changes only extend existing functionality without modifying core behavior
• All changes are additive and maintain existing API contracts

Testing suggestions:

1. Connect to MariaDB (or any database)
2. Create fields of different types (TextArea, URL, JSON, Number, Markdown, RichText)
3. Open context menu for each field type and verify "Display copy button" option appears
4. Enable copy button for different field types and verify functionality works
5. Test with both new and existing Input fields to ensure backward compatibility
