## Files Changed

### Frontend
| File | Change |
|------|--------|
| `AgentUpdates.tsx` | Install button wired to `updateApi.installUpdate()`, Logs button wired to `updateApi.getUpdateLogs()`. Loading states, toast notifications, logs display panel added. |

### Server
| File | Change |
|------|--------|
| `downloads.go` | Signed package DB lookup wired (F-E1-1). Queries `GetSignedPackage` when version parameter provided. |
| `security_settings.go` | `GetSecurityAuditTrail` now queries `security_settings_audit` table (F-E1-7). `GetSecurityOverview` placeholder comment updated — raw pass-through is correct design (F-E1-8). |
| `security_settings_service.go` | Added `GetAuditTrail(limit)` method, added `models` import. |
| `queries/security_settings.go` | Added `GetAllAuditLogs(limit)` query function. |

## Notes

- `installUpdate` and `getUpdateLogs` already existed in `api.ts` — only the UI buttons needed wiring.
- No frontend test framework exists (no vitest/jest in package.json). Frontend tests are a TODO for E-1b.
- F-E1-8 resolved as "working as intended" — the settings overview raw pass-through is correct; the dashboard overview is a separate endpoint (`SecurityHandler.SecurityOverview`).
- All server tests pass. No regressions.
