feat(loan-products): add Loans A/C extension fields (collateral, eligibility, repayment, rate source, prepayment)

Stores the Loans A/C (EMI) wizard's fields that have no home in
Fineract's core loan-product schema on the same per-product satellite
used for Advances: collateral/guarantor rules, borrower eligibility,
disbursement, repayment mode, rate source / floating reset, and
part-prepayment/foreclosure. Columns are loan_-prefixed so they never
collide with the Advances columns on the shared table.
