test: add pyright ignore directives for dependency injection tests

Added pyright configuration comments to suppress expected type checking
warnings in test files that use the Depends pattern.

The Depends pattern inherently has some type checking limitations that are
expected and acceptable in test code:
- reportUnknownMemberType: ContentBlock type narrowing
- reportArgumentType: Depends marker type inference
- reportUnknownVariableType: Generic type inference in tests

These are runtime-tested patterns that work correctly but have some
static type checking limitations in strict mode.
