Implements a new UI to show recommended image counts for ML training.
Uses color-coded indicators (orange/green/blue) for Functional, Solid,
and High-Accuracy thresholds across all 28 training categories
(Foil, Stamp, and Condition models). Critical damage types (Inking,
Rips, Water Damage) carry higher recommended counts to minimise false
positives on NM grades. Accessible via a "?" toolbar button in Library.
Bumps app version to 1.1.0.
