fix: use project version in x_generator tag for accurate CVE tracking

The x_generator.engine field in published CVE records was using
client._version from cveClientlib.js (stuck at 1.0.15) instead of
the project version from cveInterface.js (currently 1.0.25).

This means every CVE record published by cveClient has been stamped
with "cveClient/1.0.15" regardless of the actual version in use.
Fixing this allows us to:

- Accurately track which version of cveClient CNAs are using
- Identify CNAs running outdated versions and reach out about upgrades
- Measure adoption of new releases across the CNA community

The fix replaces the conditional client._version lookup with the
global _version constant that stays in sync with CHANGELOG.md and
package.json.

Also removes tests for getadp/deleteadp methods that were removed
in PR #45.
