Where does the admin go to manage the library of signatures and stamps that the issuance wizard picks from? Three options below.
New menu item under Setup → Signatures & Stamps. Full-page CRUD for both libraries. Each entry has: image upload, display name, role label (signature only), default flag.
Existing /admin/company-profile gets two new sections: "Saved Signatures" and "Saved Stamps". Same grid + upload UI as Option A but lives inside the company settings page.
No preset storage. Each time admin issues a contract, the wizard shows the current CompanyProfile signature/stamp + a "Replace" button for one-time override. Nothing saves.
