**Problem:**
Pricelist page showed empty list in offline mode even though
local pricelists existed in SQLite cache.
**Solution:**
Modified PricelistHandler.List() to fallback to local pricelists:
1. Check if server list is empty (offline)
2. Load from localDB.GetLocalPricelists()
3. Convert LocalPricelist to summary format
4. Add "synced_from": "local" field
5. Add "offline": true flag
**Response format:**
```json
{
"offline": true,
"total": 4,
"pricelists": [
{
"version": "2026-02-02-002",
"created_by": "sync",
"synced_from": "local",
"is_active": true
}
]
}
```
**Impact:**
- ✅ Local pricelists visible in offline mode
- ✅ UI can show cached pricelist versions
- ✅ Users can browse pricelists without connection
- ✅ Clear indication of local/remote source
