feat: separate skill value/max (transcendence pool vs level)

- skill.value = spendable transcendence pool (editable select)
- skill.max = max level (locked by default, unlock btn)
- computeRollFormula/computeResults/confront use skill.max
- clamp transcendence spend to skill.value
- resetTranscendence button in Bio&Notes
- v14 compat: duplicate→deepClone, mergeObject→spread, socket fixes
- Dialog v1 removed, DragDrop dedup, await fixes
