refactor(i18n): name gallery filters by property instead of "Show X"

The bool filters are tri-state (All / Yes / No), so a verb-prefixed
label read as a double negative: "Show missing" set to No. Name them
after the property being filtered, matching the "Has saves" trio that
already did.

Several labels also named the wrong thing. "Show verified" is a DAT
hash match via Hasheous, not a generic verification, and "Show missing"
is specifically missing from disk.

The section heading becomes "Properties" so it sits parallel with the
drawer's other two headings (Platforms, Tags), and its key is renamed
to match. Also corrects the RetroAchievements casing, which disagreed
with every other string referencing it.

These keys are shared with the v1 filter drawer, so its labels change
too.
