feat(shares): route dividend cash claims through cashier token disbursement

Cash claims now require a token at claim submission; a cashier redeems
it at Transaction Entry to record physical hand-over, mirroring the
existing clerk-withdrawal-request flow -- no double-disbursement, and
the manager never hands over cash directly at approval time.

Also: dividend-claim tokens fall back through the same TOK. NO. lookup
used for withdrawal requests, silenced against the global error
interceptor since the caller already handles every outcome; the account
summary card now shows "Dividend Claim" instead of a misleading "A/c
Savings" label when resolving one; and cash amounts are floored to
whole rupees client-side to match cash's whole-rupee denominations.
