Threads an optional `source` through DraftInput/insertDocRow (default 'hq',
preserving current behaviour when omitted), tags module renewals as
'module_renewal', and adds generateBulkSmsPurchaseQuote — an ad-hoc bulk SMS
credit top-up priced via the existing usage rate card, tagged
'bulk_sms_topup' so the client-detail document list can distinguish it from a
subscription renewal. New route: POST /client-modules/:id/bulk-sms-quote.

renewalsDue(from,to,today): unified list of module (client_module.next_renewal,
priced by the dated price book) + AMC (period_to, fixed amount) renewals with
amount + days-until, earliest-first. generateModuleRenewalQuote: one-click
proforma carrying the client's module kind/edition forward at the price-book
rate (AMC keeps its existing renewal-invoice). Routes GET /renewals,
POST /client-modules/:id/renewal-quote. Renewal reminders already fire from the
scheduler (renewal_due/amc_expiring) — this is the worklist + action. Tests green.
