refactor(workspace): remove unused WorkspaceFileSource enum

Remove source tracking that was never used for actual logic (YAGNI):
- Remove WorkspaceFileSource enum from schema
- Remove source, sourceExecId, sourceSessionId fields from UserWorkspaceFile
- Update all related Python code to remove these parameters

The enum conflated "who triggered" with "how created" making it unclear
what value to use for edge cases. If source tracking is needed later,
it can be added back with actual requirements.
