Main menu buttons, the confirm dialog, battle menu/HUD text, backpack
tab labels, the loading/autosave indicators, and the settings tab
placeholders were all raw English literals bypassing translation.
Loads each through assetLocaleGetString like the rest of the UI, adding
new Init hooks for uibattlehud/uiautosave/uiloading where none existed,
and adds the corresponding message ids to en_US/es_MX/jp_JP.po.
Also widens the settings placeholder buffers to 64 bytes - the es_MX
and jp_JP translations overflowed the previous 32-byte size.
