  Fix SIGSEGV in HPLC SAXS get_peak: use file, not wheel_file, for end-range clamp

get_peak() operates on its `file` argument, but the gauss-fit-end range
clamp compared the typed value against f_qs[ wheel_file ].back() instead
of f_qs[ file ].back(). During Repeak, wheel_file is stale or empty (it is
never set in repeak()), so f_qs[ wheel_file ] default-inserts an empty
vector and .back() dereferences nullptr-8 (0xfffffffffffffff8), crashing.

The check is now symmetric with the start-range clamp above and with its
own body on the next line, both of which key on `file`.
