test: use SQLite sessions in controllers service api

[asukaminato0721]

Summary

Split 013 of 077 from #38784. This PR scopes the SQLite-session migration to controllers service api.

Files

• api/tests/unit_tests/controllers/service_api/app/test_app.py

Authored scope

• 954 changed lines (361 additions, 593 deletions)
• 1 files

Temporary upstream autofix

The upstream autofix.ci workflow adds dify-agent-runtime/README.md (6 additions, 6 deletions) to every API PR. That shared bot diff will disappear here after #38784 merges.

Dependency

Depends on #38784. The target tests passed with that foundation applied; this branch stays based on main so its authored diff remains minimal.

Validation

• Ruff passed for every changed Python file in the split series
• Target tests passed on top of test: use SQLite sessions in service API fixtures #38784: api/tests/unit_tests/controllers/service_api/app/test_app.py
• Full split-series run: 2122 passed

Part of #32454
