Show Existing Tags When Adding New Ones

🚀 Feature Request

Summary

When adding or editing constraints, users can assign tags manually. Currently, this can lead to inconsistencies due to typos or variations in spelling. An auto-suggestion or dropdown list with existing tags would help standardize tag usage.

Problem to Solve / User Story

As a user, I want to select from existing tags when tagging constraints, so that I don't accidentally create multiple versions of the same tag (e.g. required, Required, REQUIRED).

This improves data organization and allows for better filtering and reuse of constraints by tag.

Proposed Solution

Implement an autocomplete or dropdown feature when entering tags in the UI. The list should be populated from all tags that are already used in existing constraints.

Benefits

• Prevents tag duplication due to inconsistent spelling
• Makes constraint organization and filtering more reliable

Possible Drawbacks

The tag list might become long over time.

Additional Context

Relevant Logs or Screenshots (if applicable)

Requirements or Dependencies

Depends on whether the tag field supports autocompletion

Alternatives Considered

Optional enhancement: make tag comparison case-insensitive to avoid duplicate vs Duplicate.
