fix(i18n): translate the Street Level and Draw panels

Both panels landed after the original string extraction, so they rendered
English in every locale. Mark their markup and runtime text (status, SINCE
stops, provider tooltips, coverage meta, viewer captions, draw hints and
colours), the layer-list names kept in PANEL_LABELS, and add 90 es and ru
entries. Street Level is «Уличные снимки» / «A pie de calle».
