fix: aligner le JS avec l'API Foundry v14

- effects.mjs: remove e._getSourceName() (removed in v14, now a getter)
- fight.mjs: convert VermineCombatTracker from AppV1 (get template/getData)
  to AppV2 PARTS + _prepareContext/_prepareTurnContext
- fight.mjs: VermineCombat.rollInitiative v14 options-object signature
- hooks.mjs: renderPause -> renderGamePause; getSceneControlButtons now
  uses controls.tokens and tools record (v14 names/structure)
- roll.mjs: ChatMessage.create uses rolls array (v14 removed 'roll' key)
- item.mjs: getRollData returns system when no actor (v14 expects object)
- vermine2047.mjs: correct unregisterSheet API for ActorSheetV2
- base-item-sheet.mjs: call super._onRender
