chore(P2): V1 zombie comments cleanup + i18n events/network/items

Zombie comments (14 files):
- Replace references to deleted V1 classes (ItemBind, ItemCollar, IBondageItem,
  BindVariant, etc.) with V2 equivalents or past-tense historical notes
- "V1 path" → "legacy slot-index path" for still-active legacy codepaths
- Clean misleading javadoc that implied V1 code was still present

i18n (13 files, 31 new keys):
- Events: 12 Component.literal() → translatable (labor tools, gag eat,
  death escape, debt, punishment, grace, camp protection, chest, maid)
- Network: 12 Component.literal() → translatable (trader messages,
  lockpick jam, slave freedom warnings)
- Items: 2 Component.literal() → translatable (ItemOwnerTarget tooltips)
