Add test files and enhance logging in various components

- Introduced test files for the blossom and database packages to improve test coverage and ensure functionality.
- Updated logging practices by suppressing unnecessary log outputs during tests to enhance clarity and focus on relevant information.
- Refactored error handling in the `handle-message` and `handle-req` functions to avoid logging expected context cancellation errors during shutdown.
- Bumped version to v0.25.2 to reflect these updates.
