Pull request overview

Updates the public Brig “list team apps” endpoint to return app IDs alongside app metadata, and enhances integration-test assertions with a lightweight JSON “shape” matcher to make response validation less value-specific.

Changes:

• Change GET /teams/:tid/apps response type from [GetApp] to [(UserId, GetApp)] and propagate through Brig API + AppSubsystem layers.
• Add a JSON Shape DSL (Shape, shouldMatchShape, valueShape) to the integration test library, plus self-tests for it.
• Update/add integration tests to validate app/user retrieval scenarios using shape assertions.
