fix(obj): store Upload assignee, assigneeDate, closeDate as plain values

[Valyrian-Code]

Summary

Closes #175.

Trailing commas in Upload.__init__ wrapped three attributes in 1-tuples instead of assigning the values directly:

# before
self.assignee = (assignee,)
self.assigneeDate = (assigneeDate,)
self.closeDate = (closingDate,)

The constructor's docstring types all three as string. With the tuple wrapping, upload.assignee returned ("username",) — or (None,) when the upload was unassigned, which is always truthy and silently breaks any caller that compares or formats the value as a string.

Change

• Drop the trailing commas in fossology/obj.py:429-431 so the attributes hold the plain values.
• Add a constructor-level regression test in tests/test_uploads.py covering both the assigned ("alice") and the unassigned (None) cases. The test does not need a live Fossology server.

Compatibility

No other code in the package reads .assignee, .assigneeDate, or .closeDate (grep-verified), so nothing downstream relied on the tuple shape. The existing integration test at tests/test_uploads.py only accessed summary.additional_info["assignee"], which is why the bug slipped through the live test suite.

Test plan

• pytest tests/test_uploads.py::test_upload_assignee_fields_are_not_wrapped_in_tuples passes locally
• ruff check clean
• CI green
