Reads a CSV file written by the dashboard's tumour-board download. Returns
an empty, typed data frame when the file is missing or empty — the
contract is the same in both cases so downstream bind_rows is safe.
Value
A data frame with columns Patient, Board_Datum,
Tumorboardbeschluss, Verantwortlich, Erfasst_am. Always returns
this column set, even with 0 rows.
