fix(i18n): complete German MCP translations

[YOMXXX]

Summary

• Add missing German translations for the subconscious provider status labels.
• Add missing German translations for the MCP Server settings panel and developer menu entry.
• Restore German locale key parity with English so i18n checks and frontend i18n tests pass.

Problem

• upstream/main currently has German locale support but is missing 20 English keys.
• This fails pnpm i18n:check and the frontend i18n unit tests.
• The same main-side i18n gap is also blocking PR feat(mcp): add memory.store and memory.note write tools #2306 because its CI merge ref includes the latest main locale set.

Solution

• Added the two missing subconscious.* keys to de-3.ts.
• Added the 18 missing settings.*mcpServer* keys to de-5.ts.
• Kept the change limited to German translation chunks; no runtime behavior changes.

Submission Checklist

• Tests added or updated (happy path + at least one failure / edge case) per Testing Strategy: N/A, existing i18n parity tests covered the missing-key failure.
• Diff coverage ≥ 80% — N/A, translation-only change covered by existing i18n checks/tests; no executable logic changed.
• Coverage matrix updated — N/A: translation-only change.
• All affected feature IDs from the matrix are listed in the PR description under ## Related: N/A, no feature matrix row affected.
• No new external network dependencies introduced (mock backend used per Testing Strategy)
• Manual smoke checklist updated if this touches release-cut surfaces (docs/RELEASE-MANUAL-SMOKE.md): N/A, no release smoke surface changed.
• Linked issue closed via Closes #NNN in the ## Related section: N/A, no dedicated issue found.

Impact

• Desktop/web UI: German locale now has the same translation key coverage as English.
• No performance, security, migration, or compatibility impact.

• Closes: N/A
• Follow-up PR(s)/TODOs: Unblocks feat(mcp): add memory.store and memory.note write tools #2306 CI after merge/rerun.

🐰 Translations bloom in German text so fine,
Subconscious whispers, MCP config align,
Strings for tools and servers, labels clear,
More tongues for users drawing near! ✨

Hey @YOMXXX — thanks so much for the contribution! 🙏

The German i18n fixes were actually already applied in a prior commit (726f6c1 / 0defb51), so your PR no longer carries any net diff against main. To avoid merging a no-op, I'm going to close this one out.

Really appreciate you taking the time to submit a fix — please don't let this discourage you from contributing again!
