fix(fleetcontrol): use type conversion instead of struct literal for tag conversion

Changed from struct literal to direct type conversion when converting
EntityManagementTag to FleetControlTag, as both types have identical
structure. This resolves gosimple linter warning S1016.

- Before: fleetcontrol.FleetControlTag{Key: tag.Key, Values: tag.Values}
- After: fleetcontrol.FleetControlTag(tag)
