Fix inverted door/hopper status interpretation

Based on user testing:
- DH:1 = Closed/OK (not Open as assumed)
- DH:0 = Open/Warning

Changes:
- Invert door status trigger: fire on =0, not =1
- Update valuemap: 0=Open, 1=Closed
- Update description to reflect correct interpretation

Note: Hopper card count (OID .1.13.0) may report inaccurate values
from printer firmware - this is a hardware/firmware limitation.
