refactor: Unify types for jest tsconfigs (#3298)

This pull request updates TypeScript Jest configuration files to
centralize and standardize the declaration of custom test utility types.
The main change is moving the inclusion of
`@streamr/test-utils/customMatcherTypes` from package-level
configurations into the root `tsconfig.jest.json`, ensuring all packages
consistently include these types during testing.

### Changes

**TypeScript Jest configuration updates:**

* Added `@streamr/test-utils/customMatcherTypes` to the `types` array in
the root `tsconfig.jest.json` so that custom matcher types are available
project-wide.
* Removed redundant `types` declarations from
`packages/cli-tools/tsconfig.jest.json` and
`packages/trackerless-network/tsconfig.jest.json` to rely on the
centralized configuration.
