Fix deactivation feedback text to remove technical namespace path

Description

When users deactivate the plugin, they see a feedback modal with text that includes a technical namespace path instead of clean, user-friendly copy. The current text exposes internal code structure that users shouldn't see.

Current Problem

The deactivation feedback modal currently shows:

"We share your data with Appsero to troubleshoot problems & make product improvements. Learn more about how WeDevs_WC_Conversion_Tracking\Dependencies\Appsero handles your data."

This creates a poor user experience because:

• The technical path WeDevs_WC_Conversion_Tracking\Dependencies\Appsero looks like an error or broken code
• It exposes internal plugin structure that users don't need to know about
• It makes the plugin appear unpolished and unprofessional
• It undermines user trust by looking like something went wrong

Proposed Solution

Clean up the deactivation feedback text to use simple, professional language without any technical paths or namespace references. The text should read naturally and only mention the service name (Appsero) without showing internal code structure.

The text should say:
"We share your data with Appsero to troubleshoot problems & make product improvements. Learn more about how Appsero handles your data."

Acceptance Criteria

1. Deactivation feedback modal shows clean text without any namespace paths or backslashes
2. Only the service name (Appsero) is mentioned, not technical file paths
3. Text reads naturally like normal user-facing copy
4. No underscores, backslashes, or code-like strings appear in the message
5. The "Learn more" link still works correctly
