Add FundingTracer class that traces USDC transfers backwards from a target
wallet to identify funding sources. Key features:
- Traces funding chain up to configurable max hops (default 3)
- Identifies terminal entities (CEX hot wallets, bridges) using EntityRegistry
- Parses ERC20 Transfer event logs from Polygon blockchain
- Calculates suspiciousness scores based on funding patterns
- Supports batch tracing multiple addresses concurrently
Also adds FundingTransfer and FundingChain dataclasses to models.py
for representing funding chain data.
