CID=0 with valid MCC/MNC means the scanner found the cell but didn't
decode System Information 3/4 (which carries the Cell ID). These are
still valid towers worth displaying. Only filter when MCC=0 AND MNC=0
(truly unidentified signals).

Backend:
- Filter out CID=0 and MCC=0 entries (ARFCNs with no decoded cell identity)
Frontend:
- Move stats update before coordinate check so towers always counted
- Fix signal_strength display using null check instead of || (0 is falsy)
- Show operator name, frequency, and status in tower detail panel
- Show "Located" indicator in tower list for geocoded towers
- Fix selectTower crash when tower has no coordinates
- Update placeholder text to "Select a tower from the list"
- Add try/catch to selectTower for error resilience
Tests:
- Add tests for CID=0 and MCC=0 filtering

Parser expected pipe-delimited table rows but grgsm_scanner outputs
comma-separated key-value pairs like:
ARFCN: 975, Freq: 925.2M, CID: 13522, LAC: 38722, MCC: 262, MNC: 1, Pwr: -58
This was the root cause of no data appearing in GSM Spy.
