CampusRequest requires CLIENT_ID/CLIENT_SECRET even in device mode

[nycomp]

Problem

When using Campus with mode="device", the CampusRequest class still requires CLIENT_ID and CLIENT_SECRET environment variables, even though device mode is designed for public clients (like CLI tools) that use Bearer token authentication instead.

Root Cause

In campus_python/json_client/__init__.py, the CampusRequest.__init__() method always calls reset_authorization() which requires:

• CLIENT_ID environment variable
• CLIENT_SECRET environment variable

This happens BEFORE the caller can set Bearer authorization via set_bearer_authorization().

Expected Behavior

Device mode should:

1. NOT require CLIENT_ID/CLIENT_SECRET environment variables
2. Allow Bearer token authentication to be set via set_bearer_authorization()

Server mode should:

1. Require CLIENT_ID/CLIENT_SECRET environment variables
2. Use Basic auth with client credentials by default

Proposed Solution

1. Add a mode parameter to CampusRequest.__init__()
2. Only call reset_authorization() when mode="server"
3. In device mode, don't set any default authorization (Bearer will be set later)
4. Pass self._mode from Campus class to CampusRequest instances

Impact

This affects the campus-cli tool which uses device mode for user authentication via OAuth device flow.
