## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Replace duplicated Tools and Quellen panels in savings chat assistant messages with one combined evidence block when tool traces and generated sources describe the same data basis.
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 Assistant messages with both toolTrace and matching sources render a single Nachweis & Arbeitsweg block
- [x] #2 The combined block exposes citation source ids on the evidence rows so inline markers still point at the same evidence
- [x] #3 Sources-only assistant messages can still render a Quellen block for genuinely external sources
- [x] #4 Focused component tests, targeted lint, and build pass
<!-- AC:END -->

## Implementation Plan

<!-- SECTION:PLAN:BEGIN -->
1. Add regression tests for assistant messages where toolTrace and sources describe the same evidence.
2. Replace the separate Tools + Quellen rendering path with a single Nachweis & Arbeitsweg evidence panel when toolTrace exists.
3. Keep the Quellen-only fallback for messages that have sources without tool traces.
4. Verify focused component tests, targeted lint, and production build.
5. Commit the UI refinement; keep task In Progress until user confirms manual behavior.
<!-- SECTION:PLAN:END -->

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
Unified generated tool traces and generated sources in AgentChat. Assistant messages with toolTrace now render one Nachweis & Arbeitsweg disclosure and attach source ids to the evidence rows, so inline citation markers still resolve to the same evidence. Sources-only messages still render the Quellen fallback for external/document sources. Verification passed: npx vitest src/components/chat/AgentChat.test.tsx --run (13 tests), targeted eslint, npm run build (existing Vite chunk-size warning only).
