Update dependencies#496

@smithy/core v3.x introduced sub-path exports (/schema, /protocols, etc.)
with circular dependencies that break Jest 27's module system. When aws.js
is loaded (directly or via app.js), it initializes all 5 AWS SDK clients at
module level; any unmocked client triggers the cycle, leaving schema undefined
and crashing with "Cannot read properties of undefined (reading 'for')".
Fixes:
- Add __tests__/__mocks__/aws.js with jest.fn() stubs for all aws.js exports
- Endpoint tests: switch jest.mock("aws.js") to use factory pointing at the
manual mock, preventing the real aws.js from loading
- AWS unit tests: add stub mocks for each AWS SDK client not under test so
none of the real constructors run during module initialization
- app.test.js, error.test.js: mock aws.js since they load it via app.js
- package.json: add testPathIgnorePatterns to exclude __mocks__/ from test
