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);

DeviceEndID was uuid.UUID (non-nullable) in entity, DTO, and response.
Sending empty string from the frontend caused "invalid uuid" parse error.
Changed to *uuid.UUID throughout. CreateFishbone now skips end device
lookup, type validation, port check, and port-usage update when
DeviceEndID is nil. UpdateFishbone pointer comparisons fixed accordingly.
Run once on DB: ALTER TABLE fishbone ALTER COLUMN dev_end_id DROP NOT NULL;

- GetAllDeviceDetails, GetDevicesWithoutConnections, GetDevicesWithoutTowers
now pass nil geocoder to avoid Nominatim calls on list requests.
This reduces GET /device-details response time from ~2 minutes to <1s.
- Added sync.Map cache to nominatimGeocoder so repeated calls for the
same coordinates (e.g. GetDeviceDetailsByID) hit cache instead of
Nominatim, preventing HTTP 429 rate limit errors.
