perf: drop transaction-hash fetching across the board

Remove txHash / createdTxHash / deploymentTxHash from the schema, every handler,
and all 41 field_selection blocks in config.yaml. No event requests transaction
data now, so HyperSync does a pure log fetch with no tx join. A/B on the
gauge-dense mainnet window [10.6M -> 12M] (same 408k events): 40s vs 44s wall
clock (~9% faster) with fewer fetch ops (116 vs 136). tx hash was never used as
an entity id, so this is trivially re-addable per-event if the Curve team wants
transaction links.
