fix(i18n): complete safety-critical recovery copy in all 11 locales

[Wangnov]

Summary

• Complete native safety-critical copy for install.partial.*, settings.health.*, uninstall.status.*, and uninstall.partial.* across all 11 supported locales. Destructive and recovery actions now state their distinct consequences and interpolate the exact rendered action label.
• Add release gates that preserve placeholder parity, reject copied English/Simplified-Chinese safety paragraphs unless an exact source-bound allowlist entry exists, and keep partial-uninstall recovery actions semantically distinct.
• Exercise configuration recovery and partial-uninstall recovery in French, Arabic, Spanish, and Traditional Chinese, including RTL direction and localized confirmation/button order for Arabic.
• Keep partial-install guidance truthful after renderer loss or an ambiguous Windows invoke result: retain bounded token-keyed completion evidence, re-probe disk/managed state, and suppress reinstall until the outcome is known.
• Preserve all still-pending ancillary recovery actions when the user retries only one step, including deterministic provenance-missing branches on macOS and Windows; a successful retry can no longer erase a different unfinished cleanup action.
• Treat a successful portable fresh-install rollback as a first-class terminal outcome: clear the transaction journal, emit structured rolled-back completion evidence, and release the renderer retry guard. Missing backups remain hard failures and an ambiguous MSIX result still takes precedence as outcome-unknown.

Validation

• npm run check — pass
• npm run lint — pass

• GitHub PR checks — pass (6/6)

Deployment notes

None. No persisted-data migration is required; operation-completion evidence is bounded and process-local.

Closes #166
