fix(backend): align pytest async loop scope

[ntindle]

Why / What / How

The full backend suite still reused process-global Prisma and async Redis pools across pytest event loops after #14259. The backend already ran session-scoped async fixtures, but unscoped async tests ran on function-scoped loops by default. Stack PR #14078 added enough async coverage to reproduce the mismatch consistently: later session-scoped Copilot tests saw Prisma and Redis connections created on loops that pytest had closed.

This aligns ordinary async backend tests with the existing session-scoped fixture loop. The Graphiti subtree keeps function-scoped loops for tests backed by its explicitly function-scoped FalkorDB fixtures and per-loop ingestion state. Tests that explicitly request another loop scope retain that behavior.

Changes 🏗️

• Set asyncio_default_test_loop_scope to session in the backend pytest configuration.
• Preserve Graphiti's intentional function-loop isolation for unscoped async tests in its local conftest.py.
• Keep explicit test loop scopes and the existing session-scoped async fixture configuration unchanged.

Checklist 📋

For code changes:

• I have clearly listed my changes in the PR description
• I have made a test plan
• I have tested my changes according to the test plan:
  • Verify with pytest-asyncio 1.3.0 that ordinary unscoped async tests share one session loop
  • Verify Graphiti unscoped async tests retain separate function loops while explicit session-loop tests still share one loop
  • Run the full backend suite on Python 3.11, 3.12, and 3.13 on this dev-based PR (run 33587856499)
  • Run the full backend suite on Python 3.11, 3.12, and 3.13 with this fix applied on top of feat(platform): let a user pick the connection every new chat starts on #14078 (run 33587937958)
  • Build, smoke-test, and scan the single-container image on amd64 and arm64 (run 33587856572)

For configuration changes:

• .env.default is already compatible with my changes
• docker-compose.yml is already compatible with my changes
• The pytest configuration change is listed under Changes

Walkthrough

The backend pytest configuration now uses session-scoped test loops by default. A graphiti collection hook assigns function-scoped loops to unscoped async tests in that directory.

Changes

Pytest event loop configuration

Layer / File(s)	Summary
Session-scoped test loop autogpt_platform/backend/pyproject.toml	Adds asyncio_default_test_loop_scope = "session" to the pytest configuration.
Graphiti function-scoped loop override autogpt_platform/backend/backend/copilot/graphiti/conftest.py	Adds a collection hook that applies loop_scope="function" to eligible async tests without an explicit loop scope.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 4bca8

This change aligns backend async tests with session-scoped fixtures while preserving explicit loop scopes and the graphiti function-scope exception; no actionable merge-blocking risk remains after normal checks and review.
