The Owl web client does not suppress GTK-style mnemonics, so these
should be removed, as otherwise they are explicitly displayed.
Following GTK rules, the old GTK client would use the `_` letter
prefix in labels to underline the letter and use the corresponding
character as accelerator/mnemonic for activating the
control (https://docs.gtk.org/gtk4/ctor.Label.new_with_mnemonic.html).
The web client "supported" this feature by just ignoring and dropping
the `_` it found in labels, even after it gained support for keyboard
accelerators (= hotkeys).
The new Owl form just ignores GTK-style mnemonics entirely, not
performing that preprocessing on widget labels. As a result, the
mnemonic marker (`_`) now appears literally in some labels, and needs
to be removed.
