aztec: avoid possible overflow in comparison

Browse Source 
output/CLI/testcommon: suppress some gcc-16 (C23) warnings
  "-Wdiscarded-qualifiers" (QChar)
GUI: suppress some gcc-16 (C23) warnings
  "-Wdeprecated-enum-enum-conversion"
channel: use explicit `const struct` for precalcs instead of
  typedef (makes code more transparent)
