refactor: add # separator to display format

Display format with # separator:
- Frame: F#{number} (e.g., F#333)
- Face Trace: FS#{number} (e.g., FS#233)

Changes:
- Line 105: Frame range display (F#2219–F#2225)
- Line 143: Face Detail Modal (file_uuid:FS#233)
- Line 262: Cluster strip fallback (FS#233)
- Line 264: Cluster strip label (FS#233)

Benefits:
- # separator makes ID clearer
- Consistent format across all displays
- Visual distinction between type and number
