gas.fees: enable celo for gas fees

during the fix, looks like blockchain team has cleaned up the raw table to match other chains and the fee_currency field no longer exists

select fee_currency, *
from celo.transactions
limit 10

i don't think we can simply remove this here. our non-raw values will break without the decimal assignment, which requires the correct address to join to metadata. i have raised to the team internally again.

currently the test is failing for tx_fee_raw to equal the sum of parts within tx_fee_breakdown_raw

• tx_fee_raw:

cast(gas_price as uint256) * cast(txns.gas_used as uint256)

• tx_fee_breakdown_raw:

map_concat(
    map()
          ,case when txns.priority_fee_per_gas is null or txns.priority_fee_per_gas < 0
                then map(array['base_fee'], array[(cast(gas_price as uint256) * cast(txns.gas_used as uint256))])
                else map(array['base_fee','priority_fee'],
                         array[(cast(base_fee_per_gas as uint256) * cast(txns.gas_used as uint256))
                                ,(cast(priority_fee_per_gas as uint256) * cast(txns.gas_used as uint256))]
                         )
                end)
 as tx_fee_breakdown_raw

base_fee_per_gas comes from blocks table. maybe that doesn't align with values in transactions.gas_price?

need to investigate further. celo docs:
