Added funderAddress support for proxy wallet in TradingService

Tasks:

• Read repository guidelines (CLAUDE.md)
• Explore codebase structure
• Examine clob-client's funderAddress implementation
• Implement funderAddress in TradingService
• Update SDK and ArbitrageService to support funderAddress
• Commit and push changes
• Provide PR creation link

Changes Made:

• Added funderAddress parameter to TradingServiceConfig interface in src/services/trading-service.ts:78
• Updated ClobClient initialization to pass funderAddress parameter in both L1 and L2 auth modes (lines 188-195 and 210-221)
• Added funderAddress to PolySDKOptions interface in src/core/types.ts:126
• Updated PolymarketSDK constructor to pass funderAddress to TradingService in src/index.ts:437
• Added funderAddress to ArbitrageServiceConfig and updated TradingService instantiation in src/services/arbitrage-service.ts:58,336

Usage Example:

// Using TradingService directly
const tradingService = new TradingService(rateLimiter, cache, {
  privateKey: PRIVATE_KEY,
  chainId: 137,
  funderAddress: '0xYOUR_FUNDER_ADDRESS_HERE',
});

// Using PolymarketSDK
const sdk = new PolymarketSDK({
  privateKey: PRIVATE_KEY,
  chainId: 137,
  funderAddress: '0xYOUR_FUNDER_ADDRESS_HERE',
});

The implementation follows the same pattern as the official @polymarket/clob-client, allowing users to specify a proxy wallet address (funderAddress) for trading operations.
