feat(fixed-deposits): maturity approval UI, scoped to deposits with no closure instruction

Adds the FD Maturity Reports screen (due-without-report, generate/
approve, branch and head-office scope, detail with closure instruction
and estimated interest per deposit), a nav entry, the route, and
Branch Day Closing's maturing-today section and approval-pending
warning banner.

Adds "Matured automatically" to the maturity screen: deposits that
settled via their own Transfer-to-Savings or Reinvest instruction,
needing no approval, listed for visibility with product totals and
per-deposit detail.

Adds "Product summary" to the FD Interest Posting Reports screen
(head office): interest by product and scheme — posted through the
report, still pending, and posted directly at maturity instead — added
up to what each product has paid out in total over a period.
