Improve reset dialog (vibe-kanban) (#1466)

* Excellent! All checks pass. Let me provide a summary of the changes made:

## Summary

I've successfully implemented all the requested changes to improve the Reset Dialog:

### 1. Safety Improvements
- **Default `worktreeResetOn` to `false`** (`RestoreLogsDialog.tsx:45`) - The "Reset worktree" toggle is now off by default, preventing accidental destructive actions.

- **Added `acknowledgeUncommitted` toggle** - When uncommitted changes are detected, a new amber-colored section appears with a toggle that users must enable before proceeding. This ensures users explicitly acknowledge that their uncommitted changes may be affected.

- **Updated `isConfirmDisabled` logic** (`RestoreLogsDialog.tsx:130-133`) - The confirm button is now disabled when there are uncommitted changes until the user toggles the acknowledgment.

### 2. i18n Migration
All hardcoded strings in the dialog have been migrated to use i18n with full support for 5 languages:
- English (`en/tasks.json`)
- Japanese (`ja/tasks.json`)
- Spanish (`es/tasks.json`)
- Korean (`ko/tasks.json`)
- Chinese Simplified (`zh-Hans/tasks.json`)

The translations include proper pluralization support using i18next's `_one`/`_other` suffixes for counts.
