Translate the remaining French and Turkish

mise.toml, the comments in app/build.gradle (corrected where they no
longer described the build: the car build is signed by build-car, and
the updater reads the version from build-car's file name), OTA.md's
message table (now the updater's current English messages), the Turkish
messages quoted in CHANGELOG.md and OTA.md (glossed in English), two
test assertion messages, an icon comment, and the ignition-state comment
in EVHardware.kt. The vendored EVHardware library still has about 120
half-French comment lines; noted in SPECS.md.
