fix(auth): auth deps use their own DB session; smoke suites made dataset-independent

RUNTIME BUG (caught by live smoke tests): the global auth dependency
queried the request-scoped session, auto-beginning its transaction — any
endpoint opening 'async with db.begin()' afterwards crashed with
'transaction already begun' (POST /materials 500). get_current_user /
get_actor now resolve in a short-lived session (expire_on_commit=False
keeps the context usable detached); inventory/pm scopes keep passing the
request session explicitly.

Smoke suites rewritten against CURRENT contracts:
- assertions are behavior-based (shapes, envelopes, filters), no magic
  seed counts; dynamic lookups instead of hard-coded names/ids
- rerun-tolerant: tolerate 409-on-create by reusing prior artifacts
- aligned with current rules: revert blocked after inventory receipts
  (v2.6), attachments allowed in every status, termsheets optional at
  quote level
- SMOKE_USER/SMOKE_PASSWORD env for login (default tester/123456)

Verified on a fresh volume: migration + audit_log bootstrap, Casdoor
seed (bcrypt), demo data, and 29+76+61 smoke checks all green.
