Add helper for truncating long creator handles in list view with ellipsis

[Chucks1093]

Summary

Creator handles that are very long overflow their container in the list view. A shared truncation helper with a configurable max character count should be used wherever handles are displayed in compact contexts.

Scope

• Add truncateHandle(handle: string, maxLength?: number): string utility (default max: 20 chars)
• Append ellipsis only when truncation occurs
• Add unit tests for: short handle unchanged, exact max unchanged, one over max truncated

Acceptance Criteria

• Handles under max length are returned unchanged
• Handles over max are truncated with ellipsis
• Default max is 20 characters

ETA: 12 hours
