Address code review feedback for HuggingFace deployer

Implements 8 improvements from code review:

1. Add organization support for deploying to HF organizations
   - Added 'organization' config parameter to HuggingFaceDeployerConfig
   - Updated _get_space_id() to check organization before falling back to username

2. Add space name length validation
   - Added HF_SPACE_NAME_MAX_LENGTH constant (96 chars)
   - Validate space name length and raise DeployerError if exceeded

3. Handle space visibility updates
   - Check if space_info.private != settings.private when updating
   - Call api.update_repo_visibility() to apply visibility changes

4. Fail on invalid hardware/storage instead of warning
   - Changed hardware/storage errors to raise DeploymentProvisionError
   - Added clear error messages with documentation links

5. Use proper error types for 404 detection
   - Import HfHubHTTPError from huggingface_hub.utils
   - Check e.response.status_code == 404 instead of string matching

6. Document timeout parameter in deprovision
   - Added docstring note that timeout is unused (deletion is immediate)

7. Remove unused space_exists variable
   - Removed space_exists assignments to fix lint error

8. Update documentation terminology
   - Changed "Docker applications" to "Docker Spaces" in deployers README

All changes maintain backward compatibility and improve code quality.
