Staking pallet (index 9), FastUnstake (15), and VoterBagsList (100)
were removed from the relay chain. The relay indexer now only tracks
transfers and signed extrinsics. Added safety try-catch to staking
queries in case handlers are accidentally re-enabled.
RPC nodes run in pruned mode (~256 blocks state history).
Setting startBlock to recent blocks ensures all required
state is available. Old blocks have no significant user
transactions to index.
The event-based StakersElected handler had a bug where paged exposure
data wasn't properly extracted. Add handleRelayBlock that queries
erasStakersPaged directly from live chain state on first block to
ensure all validators and nominators are captured.
