feat(control-panel): complete the miner command center (#129)

[JSONbored]

Closes #129.

Finishes the ~70%→100% the discovery sweep flagged remaining on the miner control panel.

What

• Refresh decision pack from the web — new POST /v1/app/miner-dashboard/refresh: contributor-authed enqueue of the same decision-pack rebuild the MCP job runs, so a miner no longer has to run MCP locally to refresh. The rebuild is async, so the panel re-fetches after it lands.
• Export / download the decision pack as JSON (decision-pack-<login>-<date>.json).
• Recommendation-changelog modal — the dashboard API already attaches per-row old-vs-new diffs + re-run reasons to each next-action / repo-fit row; the inline cards truncate (2 reasons), the new modal shows the full old-vs-new diff and every re-run reason in one place.

Boundaries

Public-safe: deterministic signals only — no payout/reward/trust language. The refresh endpoint is contributor-authed (same gate as the dashboard read) and fully covered. Cross-cutting loading/empty/retry states stay tracked in #793 per the discovery sweep.

Verification

backend typecheck ✓ · UI lint ✓ · UI typecheck ✓ · UI build ✓ · backend suite 1995 passed / 1 skipped (pre-existing pngjs visual-agent skip) · UI suite 7 passed · new refresh-endpoint coverage clean (400 / 403 / 202 / session-actor paths).

Suggested action: 🛠️ Request changes. (reviewers split: request changes / merge) Address the suggestions below before merging.

Reviewer A · gpt-oss-120b — recommends 🛠️ request changes
The PR adds UI functionality for refreshing, exporting, and viewing a changelog of the miner decision pack, and introduces a new API endpoint to trigger a decision‑pack rebuild, with corresponding integration tests.

Suggestions

• Add unit/integration tests for the new MinerPanel UI components (MinerPanelActions, ChangelogDialog, collectChangelog) to meet the 97% patch‑coverage requirement.
• Verify that the Dialog component includes appropriate ARIA attributes (e.g., aria-labelledby) for full accessibility compliance.
• Consider handling non‑JSON error responses in refreshPack to avoid unhandled exceptions.

Worth double-checking

• Reduced test coverage for the newly added UI code could cause CI failures.
• Potential accessibility gaps in the new dialog if ARIA labeling is incomplete.

Reviewer B · mistral-small-3.1-24b-instruct — recommends ✅ merge
This PR adds a 'Miner Command Center' to the Gittensory UI, allowing miners to refresh, export, and view the changelog of their decision packs. The changes are well-structured and follow the project's conventions. The API and tests are updated accordingly.

Suggestions

• Consider adding a loading state or spinner for the refreshPack function to improve user feedback during the refresh process.
• Ensure that the exportPack function handles edge cases, such as when the data is null or undefined.
• Add a test to verify the behavior of the refreshPack function, including success and failure scenarios.
• Consider adding a confirmation dialog before exporting the decision pack to prevent accidental exports.
• Ensure that the changelog dialog is accessible and responsive on different screen sizes.

Worth double-checking

• Verify that the refreshPack function correctly handles authentication and authorization.
• Ensure that the exportPack function does not expose sensitive information.
• Check that the changelog dialog correctly displays the changes and reasons for re-running the decision pack.
