fix(home): align mainstage row title with "New Releases" (#741)

* fix(home): mainstage row matches "New Releases" sidebar + page label

The Mainstage row whose title chevron links to `/new-releases` was
labelled **Recently Added** (`home.recent`) while the sidebar entry and
the page itself are **New Releases** (`sidebar.newReleases`) — three
labels for the same destination. Reported on the Psysonic Discord.

Reuse `sidebar.newReleases` in both consumers (the row title in
`Home.tsx` and the section label in `HomeCustomizer.tsx`) so the
string lives in exactly one place. The now-orphaned `home.recent` key
is dropped from all nine locale files.

* docs(changelog): mainstage New Releases label fix (PR #741)
