Fix tutorial markets, M key toggle, merchant gold, and TTS fallback

- game.js: Add toggleMarket() function for M key toggle
- game.js: Update M key handler to use toggleMarket()
- npc-merchants.js: Add MIN_MERCHANT_GOLD = 500 for minimum gold
- npc-merchants.js: Fix calculateMerchantWealth to ensure min gold
- npc-voice.js: Remove browser TTS fallback - Kokoro AI only
- tutorial-manager.js: Add merchant generation for tutorial locations
