Add multi-staking entities, APY calculation, Asset Hub indexer support

- Add StakingApy, ActiveStaker, Reward entities to schema.graphql
- Add APY calculation engine in NewEra.ts (inflation curve + validator commission)
- Add saveMultiStakingReward to Rewards.ts and PoolRewards.ts
- Add handleAssetTransfer for assets.Transferred events
- Add constants.ts with genesis hashes and inflation params
- Add docker-compose.prod.yml for production deployment (relay + assethub nodes)
- Add deploy-vps.yml GitHub Actions workflow for auto-deploy on push
