fix(i18n): backfill shortcut labels for #435 in 7 locales (#436)

* fix(i18n): backfill 10 settings.shortcut* keys for #435

PR #435 added 10 new settings.shortcut* labels to en.ts (start search,
advanced search, toggle sidebar, mute, equalizer, repeat, open now
playing, lyrics, favorite current track, open help) but left the other
7 locales without translations — i18next would fall back to English at
runtime.

Adding translations for de, fr, nl, zh, nb, ru, es in the same position
as en.ts (right after shortcutOpenMiniPlayer), styled after the
existing shortcut* entries in each locale.

* docs(changelog): add #435 shortcuts action-registry entry

* chore(credits): add #435 to cucadmuh's contributions
