test: add vector watermark lifecycle integration test

Covers full workflow: employee submit → adm1 approve → adm2 approve
→ QR generation → embed API reachability → download token flow.
Embed step validated to API boundary (numpy 2.0 + Decimal compat
limits algorithm-level testing in SQLite environment).

Also fixes missing `import logging` in watermark_generate_resource.py.
