fit_props_printer
============================================

.. py:function:: petpal.cli.cli_tac_fitting.fit_props_printer(fit_props: dict, segment: str | None = None) -> None

   Nicely formats and prints fit parameter estimates and uncertainties.

   This function prints a table of fitted parameter values, standard errors and
   percent errors. If a segment label is provided, it is printed as a header
   before the table, which is useful when printing results for multiple ROIs.

   :param fit_props: Dictionary containing the fit results. It is expected to
                     contain a ``"FitProperties"`` entry with nested ``"FitValues"`` and
                     ``"FitStdErr"`` mappings of parameter names to numerical values.
   :type fit_props: dict
   :param segment: Optional label for the TAC segment (for example,
                   ROI name). If provided, the label is printed above the table.
   :type segment: str, optional
