fix-tag-processor-same-name

[csg-pr-bot]

Summary:

• Fixed an issue with tag duplication in the settings page by updating the processTags function in tag_processor.go to reuse existing built-in tags instead of creating new ones.
• This change enhances user experience by ensuring that only one instance of a tag (e.g., "jax") exists in the system, preventing classification errors.
