This function modifies the names of beta coefficients (bcoeff) by removing
dots and underscores to ensure consistent naming. If the names are already modified,
the function skips processing.
modify_bcoeff_names(bcoeff)A list containing:
The modified bcoeff list with updated names.
A tibble mapping the original names to the modified names.
A named list of beta coefficients. The names of this list are the coefficients used in the utility function.
