Refactor project structure: rename common/ to shared/ and update imports

- Renamed the `common/` directory to `shared/` to better reflect its purpose.
- Updated all relevant import paths across the codebase to use the new `shared/` directory.
- Removed obsolete constants and utility files from the `common/` directory to streamline the project structure.

-> The `common/` folder is a catch-all for things that are not specific to a single feature. It's organized by purpose, not by type/domain. That's why it can have both `errors/` (domain) and `utils/` (type) folders.

-> Avoid dumping everything into `common/` by default. If a util, constant, or interface is only used in one feature - keep it inside that feature's folder. Promote it to `common/` only when it's reused.
