feat(i18n): complete migration — items, entities, AI goals, GUI screens

119 new translation keys across 3 domains:
- Items/Blocks/Misc (46 keys): tooltips, action messages, trap states
- Entities/AI Goals (55 keys): NPC speech, maid/master/guard messages
- Client GUI (18 keys): widget labels, screen buttons, merchant display

Remaining 119 Component.literal() are all intentional:
- Debug/Admin/Command wands (47) — dev tools, not player-facing
- Entity display names (~25) — dynamic getNpcName() calls
- Empty string roots (~15) — .append() chain bases
- User-typed text (~10) — /me, /pm, /norp chat content
- Runtime data (~12) — StringBuilder, gag muffling, MCA compat
