v2.1.4

• Fix all AppV2 ship sheets throwing DataModelValidationError ("must be a number") when a number field is cleared
  • Applies to NPC ship, player ship, ship component items, and ordnance sheets
  • Extract shared coerceEmptyNumberInputs helper into scripts/sheet-utils.js
  • AppV2: override _processFormData in each sheet mixin to coerce null values from empty <input type="number"> to 0 before Foundry validates the expanded object; use querySelector+CSS.escape for reliable element lookup with dotted names
  • AppV1: _updateObject coerces empty inputs to 0 before the key-remap loop
