If I understand correctly: No, it doesn’t break the rules of music
theory. It’s totally correct (and almost always a must-have!) to have
the last bar shortened by the length of the anacrusis.

Maybe you should use a newer (“unstable”/development version); 2.19.xx
allows \partial after the start of a piece and handles bar numbers
correctly. The development versions aren’t unstable in the sense that
they will crash or damage your input files or something similarly bad
but only that there is a new version every two (?) weeks; of course you
don’t have to always use the very latest version but only upgrade if you
want to use new features.

I don’t think LilyPond does anything wrong here. Anacruses aren’t
counted as bars. Maybe you don’t want the two alternatives counted as
two bars? This can be prevented by

\set Score.alternativeNumberingStyle = #'numbers

(you might prefer … = #'numbers-with-letters).

Try

\override Score.BarNumber.break-visibility = #end-of-line-invisible

instead.

Put both of the commands above in a \layout block outside of the
\scores; then they’ll affect (or effect? I don’t know) all scores:

\layout {
  \context {
    \Score
    \override BarNumber.break-visibility = #end-of-line-invisible
    alternativeNumberingStyle = #'numbers-with-letters
  }
}

The \score blocks then simply look like this (after removing unneeded
contexts and stuff):

\score {
  <<
    \new ChordNames \PartOneChords
    \new Staff \PartOne
  >>
  \layout { }
  \midi { }
}
