feat(shares): add Share Withdrawal maker-checker workflow with GL settlement

Clerk submits a governed share redemption request (shares, Board Resolution
No., Meeting Date, settlement Payment Type); Bank Manager reviews with a
live backend-validated checklist (account/GL state, not just submit-time
snapshot) before approving, which redeems the shares and settles the
linked savings account in one transaction. Adds a Passbook tab to the
Share Account view, a reusable search-select control, and a Savings
Product "Map Payment Types to Specific Funds" fund-source override (only
Loan Products had this before) so settlement can be GL-mapped correctly.
