Print brace, clef and key signature at start of Coda separated by blank space

[Vlado Ilić]

Hello everyone, example:
\version "2.24.1"

upper = {
\key as \minor
c'1
\stopStaff
s1*4
\startStaff
\section
\sectionLabel "Coda"
c'1
\bar ".|"
}

lower = {
\key as \minor
c'1
\stopStaff
s1*4
\startStaff
\section
\sectionLabel "Coda"
c'1
\bar "|."
}

\score {
  \new PianoStaff
  <<
    \new Staff = "upper" \upper
    \new Staff = "lower" \lower
  >>
}

How can I force lilypond to print pianostaff brace, clef and key signature
at the beginning of Coda that is not on line break?
