feat: sniper bot updates — TUI separation, session scheduling, proxy support, win-only redeem

- Separate TUI from sniper: npm run sniper (console), npm run sniper-tui (TUI)
- Add trading session scheduling per asset (BTC/ETH/SOL/XRP) in UTC+8
- Add PROXY_URL support for Polymarket CLOB/Gamma/Data APIs (not Polygon RPC)
- Create redeemSniperPositions: win-only filter, bulk MultiSend batching
- Add gas estimation with 10s timeout in execSafeCall
- Replace native fetch with proxyFetch in all Polymarket API services
