Updates the Lithuanian translation for v1.4 and fills all 181 missing
strings, including the command palette entries.
Related to #13766.
Validation:
- Manually reviewed all translated strings
- `msgfmt --check --check-compatibility --check-accelerators` passes
- `msgcmp` against the translation template passes
AI usage: I used Pi with OpenAI Codex (gpt-5.6-sol) to draft the
translations and run gettext checks. I manually reviewed all
translations before submitting.
