Refactor endpoints to adhere to SOLID principles and fix CI issues.

- Introduce `_extract_special_params` hook in `ListGetEndpointMixin`.
- Refactor `UsersEndpoint` and `RecordsEndpoint` to use the new hook, removing `_list_impl` overrides.
- Refactor `RecordsEndpoint` to share creation logic between sync and async methods via `_prepare_create_request`.
- Refactor `JobsEndpoint` to share path building and parsing logic between sync and async methods.
- Create `.jules/architect.md` to document architectural decisions.
- Remove unused imports in `imednet/endpoints/users.py`.
- Upgrade `pip` to `^26.0` in dev dependencies to resolve CVE-2026-1703 flagged by `pip-audit`.
