Bug: Missing required columns in avalanche trades model

The odos_avalanche_c_trades model is missing 8 columns that odos_trades.sql expects to select via UNION ALL: token_bought_symbol, token_sold_symbol, token_pair, token_bought_amount, token_sold_amount, amount_usd, tx_from, and tx_to. Other chains (ethereum, base, arbitrum) have an odos_v2_*_trades intermediate model that joins with token metadata, prices, and transactions tables to compute these columns. The avalanche model directly queries raw event data without these joins, causing a schema mismatch that will fail the UNION operation.

renamed [odos_avalanche_c_trades.sql] to [odos_v2_avalanche_c_trades.sql]

will need to add a [odos_avalanche_c_trades.sql] separately per cursor autobot:
