fix: Remove duplicate scan logging to prevent storage/system scans on Updates page

BREAKING CHANGE: Storage and system scans no longer create entries in update_logs

**Problem**
- Storage scans were appearing on Updates page (mixed with package updates)
- System scans were appearing on Updates page (mixed with package updates)
- Duplicate "Scan All" entries from collective + individual logging

**Root Cause**
Scan handlers were calling both ReportLog() and dedicated endpoints:
- reportLogWithAck → POST /api/v1/agents/:id/logs → update_logs table
- This caused storage/system metrics to appear alongside package updates

**Fix**
Removed ALL ReportLog() calls from scan handlers:
1. handleScanUpdatesV2 (lines 44-46): Removed collective logging
2. handleScanStorage (lines 103-105): Use only ReportStorageMetrics
3. handleScanSystem (lines 189-191): Use only ReportMetrics
4. handleScanDocker (lines 269-271): Use only ReportDockerImages

**Verification**
- All 4 handlers have working dedicated endpoints (verified via subagent)
- Routes already registered: POST /storage-metrics, POST /metrics, etc.
- Frontend queries correct endpoints (verified)
- No data loss: dedicated endpoints store in proper tables

**Result**
- Storage scans → storage_metrics table → Storage page only ✅
- System scans → system reporting → System page only ✅
- Package updates → update_logs table → Updates page only ✅
- No duplicate "Scan All" entries ✅

**Files Changed**
- aggregator-agent/cmd/agent/subsystem_handlers.go: Removed 20 lines of ReportLog calls
- internal/api/handlers/agents.go: Command recovery enhancements
- internal/api/handlers/updates.go: Subsystem extraction logic
- internal/database/queries/commands.go: GetStuckCommands query

+## Summary: Why History Shows "SCAN" Generically
+
+**The Confusion You See**:
+- Each subsystem has its own "Scan" button (✅ correct)
+- But history only shows generic "SCAN" (❌ confusing)
+
+**The Implementation Flow**:
+```
+You click: "Scan Storage" button
+  → UI passes: subsystem="storage"  ✅
+  → Backend creates: command_type="scan_storage"  ✅
+  → Agent runs: handleScanStorage()  ✅
+  → Results stored: updates=[4 items]  ✅
+  → History logged: action="scan"  ❌ (should be "storage scan" or similar)
+```
+
+**Root Cause**: 
+The history table's `action` field stores only generic "scan" instead of including the subsystem context. Even though:
+- Backend knows it's "scan_storage"
+- UI sends subsystem parameter
+- Results are subsystem-specific
+
+**The Result**:
+```
+History shows unhelpful entries like:
+  [14:20] SCAN → Success → 4 updates found
+  [14:19] SCAN → Success → 461 updates found
+
+Which subsystem found which updates? Unknown from history.
+```
+
+**This is a UX Issue, NOT a Bug**:
+- ✅ Scans run for correct subsystems
+- ✅ Results are accurate
+- ✅ Backend distinguishes types ("scan_storage", "scan_system", "scan_docker")
+- ❌ History display is generic "SCAN" instead of "Storage Scan", "System Scan", "Docker Scan"
+
+**Why It Happened**:
+- Early design had simple action types ("scan", "install", "upgrade")
+- Later added docker/storage/system scans
+- Database schema never evolved to include subsystem context
+- History display just shows action field directly
+
+**Files Involved**:
+- ✅ Working: AgentHealth.tsx (per-subsystem scan buttons)
+- ✅ Working: Backend API (creates "scan_storage", "scan_system", etc.)
+- ❌ Broken: History logging (stores only "scan", not subsystem)
+- ❌ Broken: History display (shows generic text, no subsystem parsing)
