Add per-license customer secrets for API response verification

- Add static methods to ResponseSigner for deriving customer-specific secrets
- Display "API Verification Secret" in customer account licenses page
- Add collapsible secret section with copy button
- Update server-implementation.md with per-license secret documentation
- Update translations with new strings

Each customer now gets a unique verification secret derived from their
license key, eliminating the need to share the master server secret.
