Fix tag relationship processing errors

[sosyz]

Description

This PR addresses three issues:

1. Optimizes the performance of checking for new tags.
2. Fixes an issue where tag relationships had incorrect status when enabled.
3. Adds status filtering when updating tag relationships.

These changes are related to the bug reported in #1144

Changes

1. Optimized HasNewTag function in internal/service/tag_common/tag_common.go:

   • Replaced map[string]bool with map[string]struct{} for better memory efficiency.
   • Simplified the logic to check for new tags, reducing unnecessary iterations.

2. Fixed tag relationship status when enabling:

   • Added logic to consider the question's status (hidden/visible) when restoring tag relationships.

3. Added status filtering when updating tag relationships:

   • Implemented filtering to exclude deleted data when restoring hidden tag relationships.

Testing

Please test the following scenarios:

1. Unlisting a question with multiple tags
2. Editing an unlisted question (removing and adding tags)
3. Listing the question again

Verify that:

• Removed tags are not displayed after listing the question
• Tag relationships are correctly maintained when changing list/unlist status
• Performance is improved for operations involving tag checks

Additional Notes

This PR aims to resolve the issues mentioned in #1144 and improve overall tag handling in the system. Please review and provide feedback if any further changes are needed.
