`ib`: never override existing ledger records

If user has loaded from a flex report then we don't want the API records
from the same period to override those; instead just update with any
missing fields from the API schema.

Also, always `str`-ify the contract id (what is set for the `.bs_mktid`
*before* packing into transaction type to ensure when serialized to
`pps.toml` there are no discrepancies at the codec level.. smh
