feat(TagsList): sort tags alphabetically and update related logic

[dganesh05]

fix(tags): display tags in alphabetical order

SUMMARY

Fixes inconsistent tag ordering by implementing alphabetical (case-insensitive) sorting in the TagsList component. Previously, tags appeared in unpredictable order as received from backend/state. The sorting is memoized for performance and automatically applied to all views.

TESTING INSTRUCTIONS

1. Navigate to Dashboard list, Chart list, or Saved Query list in Superset
2. Identify items with multiple tags (or add tags: "Zebra", "Apple", "Marketing", "Beta")
3. Verify tags display in alphabetical order (case-insensitive): "Apple", "Beta", "Marketing", "Zebra"
4. Reload the page and confirm ordering remains consistent
5. Check tags across different items/views to ensure consistent ordering
6. Test with special characters (e.g., "!tag", "@tag", "#tag") to verify sorting behavior

ADDITIONAL INFORMATION
