Enhance deacon, witness, and refinery status lines

Deacon:
- Now shows both rig count and polecat count
- Added mail preview (40 chars)

Witness:
- Shows polecat count and crew count (if any)
- Added mail preview (35 chars)

Refinery:
- Shows current item being merged (issue ID) instead of generic +1
- Shows queue count when items pending
- Added mail preview (30 chars)
