That depends pn what you mean by `not installed properly`. If it is undersized you may continually kill blower motors and/or heat exchangers, have noise issues and of course not heat or cool the home properly.
It depends. If your bedroom has a supply AND return duct, then no. If there is only a supply duct, and you shut your bedroom door, this pressurizes the bedroom and limits the CFM delivered into the bedroom. A room to room vent or duct would equalize this pressure and allow maximum CFM to be delivered from the central air/heat system.
Sure, ductwork only carries hot air from the source to the living space. It does not matter what the source is.
It contains the heart, the great vessels of the heart, esophagus, trachea, phrenic nerve, cardiac nerve, thoracic duct, thymus, and lymph nodes of the central chest
The air is returning at a lower velocity, so you need a larger size duct.

Of course it is. The unfortunate part is that because it is so historic, you will have to new duct work installed, which will cost you a lot of money.
Try a Google search on ACCA Manual D and you can figure it properly.

If your apartment does not have duct work, the owner of the building has not had it installed. Perhaps they felt it would be too costly to install, or perhaps they are simply not interested in or see a need for duct work.

The IAT sensor is installed in the intake air duct
Only if properly placed or wrapped on it.

Heat cannot escape the duct as easily as in open air. This results in the same amount of current causing the cable to heat to a higher temperature.
Limited duct cleaning can be a DIY project. By removing the duct vents and cleaning them and vacuuming in the vent, you can get quite a bit of dust removed. However, only a professional cleaner can get at every inch of your ducts.
