fix(deposits): enforce savings-only maturity transfers and fix duplicate GL posting on FD/RD closure

Adds validation so Transfer-to-Savings can only target a real savings account,
with a proper user-facing message instead of the generic validation error.
Fixes three duplicate journal-entry bugs uncovered while testing FD/RD
maturity: the dormant-accounts job re-posting already-closed accounts
(escheat/setSubStatusInactive/setSubStatusDormant), and the maturity-closure
flow itself re-deriving accounting for a withdrawal that the account-transfer
service had already posted.
