fix(migration): recover transaction type labels and minimum balance

Two fields the customer-facing site reads were being dropped on the way in
from Access.

transform_transactions.py mapped DATOS2's type string through the Access
`TYPE OF TRX` table and stored NULL on a miss. That table is a stale
pick-list rather than a constraint — staff free-text straight into DATOS2 —
so 78 distinct values covering 3,939 rows never resolved, including
BALANCE FORWARD (1,188) and ANNUAL FEE (1,116). Nothing else on
`transactions` carries the type text, so those rows lost their label
outright and rendered blank. Now mints a type_transactions row from the
literal string when the lookup lacks it; nameEs stays NULL since only the
lookup has translations.

transform_customers.py never carried DATGRAL.TIPO, leaving
customers.minimumBalance empty on every row despite the column existing.
TIPO is the minimum-balance threshold (100/200/300/500; 1,017 of 1,172
customers carry one), not an account type as the name suggests — the
customer app shows it as `minBalance`. Added to the insert list and to the
ON DUPLICATE KEY UPDATE clause, without which --sync would silently skip
it on existing rows.

Both land on the next `run_all.py --sync` reload.
