refactor: extract MdrsClient service layer for library portability

To improve the tool's portability as a Python library, the core logic
has been decoupled from the CLI interface. This allows developers to
programmatically interact with MDRS without relying on CLI-specific
argument parsing or local file-based caches.

- Introduce `MdrsClient` service layer to handle core operations.
- Abstract authentication state using `CacheInterface` and `InMemoryCache`.
- Migrate all CLI commands to utilize `MdrsClient` for execution.
- Separate `Doi` data model from API responses and move to `models/doi.py`.
- Update `README.md` to include Python API usage examples.
- Bump package version to 1.3.17.

Python API Usage

You can also use this package as a Python library to programmatically interact with MDRS repositories.

from mdrsclient.client import MdrsClient
from mdrsclient.cache import InMemoryCache

# 1. Setup client with an in-memory cache to avoid local `.mdrsclient` state files
cache = InMemoryCache()
client = MdrsClient.from_remote("neurodata", cache=cache)

# 2. Login to the remote server
client.login("username", "password")

# 3. Use service methods
labs = client.get_laboratories()
metadata = client.metadata("neurodata:/NIU/Repository/")

# Transfer files programmatically
client.upload("/path/to/local/data", "neurodata:/NIU/Repository/TEST/", is_recursive=True)
client.download("neurodata:/NIU/Repository/TEST/data", "/path/to/local", is_recursive=True)
