chore: upgrade deps and CI

[Puppo]

This pull request updates the CI configuration and development dependencies to support newer versions of PostgreSQL and to keep dependencies up to date. It also updates the way the sqlmap repository is cloned for security tests.

CI/CD improvements:

• Updated .github/workflows/ci.yml to run tests against PostgreSQL versions 14, 15, 16, 17, and 18, instead of a single old version, ensuring compatibility with newer database releases.

Dependency updates:

• Upgraded several development dependencies in package.json, including @fastify/postgres, async, fastify, jsonfile, pg, and standard, to their latest versions for improved performance and security.

Security testing improvements:

• Replaced the use of napa with a direct git clone for fetching the sqlmap repository in the pretest:security script, simplifying dependency management.
