Add a small single-pass helper, Koha::Regex::Replacement::expand_template,
that expands a user-supplied regex replacement string as data: numbered
backreferences ($1..$n, ${n}, the legacy \1..\9 form), named captures
($+{name}, ${name}) and the \n \r \t escapes. Every other character is
copied through literally, so \@{...}/${...} interpolation blocks end up as
text rather than being run. This is used to replace the s///ee double-eval.
The routine is fully qualified at the call sites rather than exported, and
case folding is left out to keep it small.
