feat: KYC re-verify UX, family/nominee tab gating, savings dialogs, cfcfrms shell

- KYC tab: fix Verify (PAN) and Send OTP (Aadhaar) being disabled in edit mode;
  unmask Aadhaar input and show on-file masked value as hint; resolve kycId
  from id/kycId/resourceId fallbacks.
- Client stepper/view: add familyAllowed / nomineeAllowed predicates +
  CanActivate route guards. Family tab hidden for non-individuals, Nominee
  tab hidden for non-proprietor entities. Family-members step accepts a
  nomineeOnly input for proprietorship clients. Add/Edit/Delete buttons
  inside family-members and nominee tabs gated by canAdd.
- cfcfrms: add cfcfrms-shell wrapper, restyle complaint/fraud/mule/escalate
  pages and dashboard.
- Savings: identity-verify and transaction-confirm dialogs, manage / activate
  / add-charge flows, account preview styling.
- Tasks, core shell, account-nominees, icons: minor style and behaviour
  updates.
