thorchain: update model logic

[jeff-dude]

Note

Refactors Thorchain silver models to normalized, day-based schemas and rewrites gold fact models to join core blocks with new surrogate keys/partitioning, adding thorchain_core_transfers and extensive schema tests.

• Pipeline standardization (Silver):
  • Normalize inputs, deduplicate via row_number, and standardize columns (block_timestamp, day) across silver models (add/bond/swap/stake/withdraw/events, prices, block_log, pool depths/fees/stats, rewards, transfers, TVL, block rewards).
  • Materialization/partitioning changes: several models switched to table/view; keys/partitions moved to day; removed legacy time columns; recalculated daily aggregates.
  • Reworked pricing and daily computations (prices, block_rewards, daily_earnings, daily_tvl, pool_block_statistics) to use day-level logic.
• Facts (Gold):
  • Update all gold DeFi fact models to:
    • Join thorchain_core_block for dim_block_id, use block_timestamp incremental predicates, and new surrogate keys.
    • Partition by day where applicable and adjust unique keys.
  • Add thorchain_core_transfers and remove legacy thorchain_defi_transfers.
• Schema/tests:
  • Overhaul _schema.yml with unique-combination tests aligned to new keys (primarily day + id/_unique_key).
