Set up environment variables and Firestore collections for pool creation feature.

Tasks

Mobile Environment Variables

• Add EXPO_PUBLIC_POOL_FACTORY_ADDRESS_AMOY to apps/mobile/.env
• Add EXPO_PUBLIC_BACKEND_URL for Firebase Functions
• Update chain configurations with PoolFactory addresses

Firestore Collections Setup

• Create pools collection with composite key ${chainId}-${poolId}
• Create event_sync_state collection with document per chain
• Set up Firestore security rules for read/write permissions
• Add indexes for common queries (chainId, poolOwner, createdAt)

Collection Schemas

pools

Document ID: ${chainId}-${poolId}
Fields: {
  poolId, poolAddress, poolOwner, name, description,
  maxLoanAmount, interestRate, loanDuration,
  chainId, createdAt, transactionHash,
  blockNumber, isActive
}

event_sync_state

Document ID: ${chainId}
Fields: {
  chainId, lastProcessedBlock,
  lastSyncedAt, totalPoolsIndexed
}

Acceptance Criteria

• All environment variables configured and documented
• Firestore collections created with proper schema
• Security rules enforce proper access control
• Indexes optimize common query patterns
