fix: handle baseDescription fallback for all node types in parsers

Browse Source 
Fixes VersionedNodeType parsing failures where test mocks only have
baseDescription without the description getter that real instances have.

Changes:
- Add baseDescription fallback in regular (non-VersionedNodeType) paths
- Check instance-level baseDescription/nodeVersions for versioned detection
- Prevent fallback for incomplete mocks testing edge cases

This resolves 11 test failures caused by v2.17.5 TypeScript type safety
changes interacting with test mocks that don't fully implement n8n's
VersionedNodeType interface.
