"""Playwright e2e tests for OAuth credential injection in routines.

Tests the full flow for issue #999:
1. Complete OAuth for a WASM tool (gmail)
2. Create a routine that calls that tool
3. Manually trigger the routine
4. Verify the tool executes with proper credential injection (no 403 errors)

This tests that OAuth tokens stored globally under 'default' user are properly
