- 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

CreateTower and UpdateTower multipart handlers were building the DTO
without reading backbone_code from PostForm, so the field was always nil
even when the frontend sent it. Added c.PostForm("backbone_code") parsing
in both handlers.
