[SDK] Test coverage TOOL-2241 (#5826)

Holiday project.
Basically trying to improve test coverage, especially in those low-haning-fruit utils files

<!-- start pr-codex -->

## PR-Codex overview
This PR focuses on enhancing documentation, improving error handling, and adding tests across various modules in the codebase. It also corrects minor typos and ensures better code readability.

### Detailed summary
- Added `@internal` documentation comments to `Queue` and `convertViemChain`.
- Updated test cases to use `await expect(...)` for consistency.
- Fixed typos in file imports and function names.
- Introduced new tests for `namehash`, `encodeLabelhash`, and `parseNFT`.
- Enhanced error handling in `parseNftUri`.
- Improved the `toSemver` function and its tests.
- Added tests for `replaceBigInts` and `toHex` functions.
