* fix: omit coarse metric pitch from generated designations
* Keep custom tapped-hole nominal diameter and pitch editable
Preserve Custom as dialog state, derive the existing metric designation from numeric inputs, and refuse invalid drafts without applying the last valid size. Retain manual text editing, physical tap-drill geometry and saved-design compatibility.
