stop the framework carrying file-browser vocabulary

`initialFilePath` and `defaultFileSort` were declared on the workspace context, plumbed through
`WorkspaceView`'s props and read by exactly one panel wrapper — and set by zero callers. The sort
shape in particular (`{field: 'name'|'size'|'type'|'date', direction}`) is file-browser vocabulary
sitting in the framework's type file and re-exported from two barrels, so every app that imports the
context could see it.

Nothing changes at runtime: both were always undefined, which is what the wrapper now passes by
omitting them.
