From the Waiver Request linked from the article in the question: The Boeing 702HPspacecraft design features a reaction wheel pointing control system. As all venting must occur within the capabilities of this pointing control system, the firing of thrusters for venting and to address momentum buildup must be of more limited duration and additional time is ...

The thing you are describing is usually studied under the term 'relativistic rocket'. Here is a good summary of the formulae you need. All of these can be derived using Special Relativity (it is a common myth that you need General Relativity to deal with acceleration: you don't, you need it to deal with gravity or equivalently non-flat spacetimes). One ...

A gee for a day is 9.8 m/s^2 x 86400 seconds = 846720 m/s, which is only 0.0028 of the speed of light. The most efficient engines now possible would be hydrogen-oxygen chemical rocket engines; electric thrusters are more mass-efficient but can't produce enough thrust to achieve 1 g acceleration. Assuming an exhaust velocity of 4400 m/s, the rocket ...
