chore: pre-release cleanup — remove debug logs, fix clippy warning, add missing ja translations, and format code

- Remove 2 console.log statements from DeepLinkImportDialog
- Fix clippy unnecessary_map_or: use is_some_and in live.rs
- Add 17 missing Japanese i18n keys (skills, proxy, circuitBreaker, universalProvider)
- Run prettier and cargo fmt to fix pre-existing formatting drift
