📝 Full Task Prompt

## Objective
Translate the operational Settings categories and their dialogs while preserving all saved enum values, validation rules, destructive confirmations, and runtime behavior.

## Scope
- Create `dashboard/src/v2/i18n/messages/settings-operations.ts`
- Edit `SettingsGeneralPanel.tsx`, `SettingsSprintPanel.tsx`, `QAPanel.tsx`, `AutomationPanel.tsx`, `WorkerPanel.tsx`, `SettingsBrowserPanel.tsx`, and `SettingsDangerPanel.tsx` under `dashboard/src/v2/components/settings/panels/`
- Edit `dashboard/src/v2/components/settings/BranchNameSchemeEditor.tsx`, `SprintKeyEditor.tsx`, `PrTemplateEditorModal.tsx`, `LocalFilePickerField.tsx`, and `OpenSourceSoftwareModal.tsx`
- Edit presentation metadata in `dashboard/src/v2/lib/settings/branch-naming.ts`, `dashboard/src/v2/lib/open-source-software.ts`, and related operation display helpers
- Update corresponding tests under `tests/dashboard/v2/`, `tests/dashboard/settings/`, and settings component tests

## Implementation Requirements
1. Translate every static label, description, option caption, status, validation fallback, confirmation, helper, accessible name, and empty/loading state in the owned panels.
2. Map translated option labels to the existing stable automation, Git, QA, guardrail, branch, browser, logging, restart, cleanup, and danger-zone values without translating serialized values.
3. Keep filenames, paths, branch tokens, PR templates, command examples, dependency names, license metadata, API errors, and runtime diagnostics verbatim inside translated surrounding copy.
4. Cover invalid numeric/text inputs, unavailable project context, pending duplicate suppression, destructive confirmation, failed saves, file-browser failure, and focus restoration in both locales.

## Constraints
- Do not edit shared Settings shell files owned by T04 or other category panels.
- Do not translate default instruction templates or other content consumed by workers at runtime.
- Preserve secret redaction, destructive-action gating, async feedback semantics, and existing API calls.
- Keep documentation destinations English-only and unchanged.

## Verification
- Run focused tests for General, Sprint, Browser, Danger, branch naming, QA, open-source software, and Settings controls.
- Run `pnpm run lint`.
- Run `pnpm run test:dashboard`.
- Run `pnpm run build`.
- Success means all owned controls render German UI while saved payloads, validation boundaries, and runtime-facing template content remain unchanged.
