The earlier 'Currently on file' indicator hung off readonlyValue, which
is sourced from evalState (only carries current_stage). For file fields
the prefill lives in RHF state, not in evalState, so the indicator
never fired.
Replaced with a FilePriorIndicator subcomponent that subscribes to the
field's RHF value via useWatch and renders a small leaf-50 banner with
a paperclip glyph when a previous attachment is present. Falls silent
the moment the user picks a new file (RHF value becomes a FileList).
Filename is derived from whatever shape Civi returned — bare string,
object with file_name/name/label/filename, or numeric file id (generic
message in that case).
