Merge origin/main: GNSS integrity, geo file import and cockpit emergencies meet i18n

Conflicts resolved by keeping both sides: the Events group gains
gnss-integrity with a translated label, the cockpit aircraft line shows
main's transponder emergency through a localized formatter (cockpitMath.js
stays i18n-free, like the Context scope line), and the boundary lists keep
both the i18n modules and main's new data modules.

Main's new UI is translated into es and ru: the GNSS Integrity row, legend
and notes; geo file import (button, hints, list actions, every import
error, with numbers passed as placeholders); transponder status names.
Also formats kartaview/viewer.js so format:check passes.
