Add SSH scan support with BSI TR-02102-4 compliance

- SSH scanning via ssh-audit (KEX, encryption, MAC, host keys)
- BSI TR-02102-4 and IANA compliance validation for SSH
- CSV/Markdown/reST reports for SSH results
- Unified compliance schema and database views
- Code optimization: modular query/writer architecture
