- Ubah map key dari "BackboneCode" ke "backbone_code" di UpdateTowerWithMultipleImages
agar GORM memetakan ke nama kolom yang benar di database
- Ubah c.PostForm("device_id") ke c.PostForm("dev_id") di UpdateTower controller
agar konsisten dengan key yang dikirim frontend dan handler CreateTower

Towers can now be explicitly assigned to a backbone by setting
backbone_code. This field is included in create/update DTOs and
the response. The backbone OSRM routing merges these tower waypoints
with Closure waypoints, sorted by distance from OTB-start.
Run once on DB: ALTER TABLE towers ADD COLUMN backbone_code VARCHAR(255);
