fix: fix: protocol activity statistics stay zero — ponder watches wrong contract addresses (#4)

Browse source 
1. Add LM_ADDRESS and POOL_ADDRESS to ponder .env.local (bootstrap.sh)
2. Discover pool address from Uniswap factory during bootstrap (bootstrap-common.sh)
3. Make ring buffer block threshold configurable via MINIMUM_BLOCKS_FOR_RINGBUFFER env var,
   set to 0 for local dev so early events populate the ring buffer
