feat(cashier): restore Share Redemption Transfer support in Transaction Entry

This entire feature — submitting a governed Share Withdrawal Request
directly from a Bank Transfer's DR(Share)/CR(linked savings) row pair
— was silently dropped from demo-backup during the dev merge's auto-
resolve, even though the feature files it depends on (clerk-share-
withdrawal.service.ts) were present. Restores: paymentTypesForRow()
(hides cash payment types for Share rows and their settlement CR
row), the SHARE NO./RESOLUTION NO./MEETING DATE fields (replacing
AMOUNT/CHEQUE NO./CHEQ. DATE for Share rows), rowSharePrices/
rowClientIds/rowLinkedSavingsAcNo tracking, submitShareRedemptionTransfer()
+ its confirm/submit flow, syncShareLinkedAmounts() auto-fill, the
Share-aware ecsAcNo/currentBalance logic, the Other Information panel's
Share-specific fields (No. of Shares Held, Market Price/Share,
Resolution No., Linked Savings A/C No.), and the SHR guard blocking
the generic Deposit/Withdrawal Slip flow for Share accounts.
