fix: restore content silently dropped from the dev merge (KYC exception, TDS reports, Form 121)

The demo-backup merge's git 3-way auto-resolve dropped several hunks
without flagging conflicts, wherever demo had independently touched
adjacent lines: the KYC Exception feature (client-kyc-step, kyc-tab,
create-client, clients.service — checkbox, derivation logic, banners,
contact-log endpoints), TDS report routes/menu links (reports-routing,
shell), the Form 121 client tab (clients-routing, clients-view), the
kyc-management exceptions dashboard, and the Form 121/15G-H register's
real-data view integration. Restored by diffing demo-backup against
dev per file and re-applying each genuine gap while preserving
demo-backup's own independent work (Approval Center tab style, Loan
Origination/Investment menus, form-97-98/risk-review report routes).
