Optimize RPC Usage - 80-90% CU Reduction (Needs live testing)

Comprehensive optimization of Ethereum RPC calls to reduce Alchemy Compute Unit usage by
implementing caching, batching, and smart polling strategies.

Changes:

• Block number caching (5s TTL) in StakerMonitor
• Gas price caching (30s TTL) in BaseExecutor
• Event query batching replacing 13 individual calls with 2 batched calls
• Multicall pattern for unclaimed rewards reducing individual contract calls
• Simulation result caching (5min TTL) for Tenderly API
• Receipt polling optimization with exponential backoff
• Optimized polling intervals and query patterns

Impact:

• Reduces RPC calls from ~100/minute to ~20/minute
• Maintains full functionality while cutting infrastructure costs
• Backward compatible with existing configuration
