2025 social security and pension parameters

[Eric-Sommer]

What problem do you want to solve?

addresses #806 by adding changes to social security contributions and pensions .

To be discussed:
There is no differentiation anymore between East and West Germany with regard to social security and pensions. The easy way (as done here) is to set the east and west parameter identical henceforth. Alternatively, we could create new functions which ignore the wohnort_ost variable.

Thank you, looks great!

I think the increase of the Pflegeversicherungsbeitrag (0.02 pp) is still missing. Or is this not official yet?

Regarding the differentiation of east/west. We should definitely create new functions that do not require the wohnort_ost Variable. However, we should postpone this for now as #804 makes huge changes to nearly every part of the codebase (i.e. changes the module these function's live in). I created #810 such that we don't forget.

pflegeversicherung increase is implemented as well
