clean up env vars: remove obsolete, add missing

Commented out unused environment variables in .env.example:
- VITE_MARKET_RELAYS (market uses VITE_NOSTR_RELAYS instead)
- VITE_SUPPORT_NPUB (config.support.npub never consumed)
- VITE_LIGHTNING_ENABLED (config.market.lightningEnabled never consumed)
- VITE_MARKET_DEFAULT_CURRENCY (config.market.defaultCurrency never consumed)

Added missing environment variables to .env.example:
- VITE_APP_NAME (used in market module)
- VITE_LNBITS_DEBUG (used in lnbits config)
- VITE_WEBSOCKET_ENABLED (used in app config)

Also commented out corresponding unused config in src/lib/config/index.ts:
- MarketConfig.lightningEnabled and defaultCurrency
- AppConfig.nostrclient (defined but never used)
- AppConfig.support (never consumed)

Removed legacy VITE_API_BASE_URL fallback from WalletWebSocketService.ts
