If the the historical lies of Cohen are admissible and to be considered by the jury, why wasn't Trump's well-documented history of lying examined in court; his lies about election rigging/fraud are obviously relevant as to intent to lie and cheat to get reelected.

Because Trump did not testify. You can use a past history of lies to impeach a witness, to show that they are not credible. But as a general matter, you cannot use prior past acts of a defendant to try to show that they are more likely to have committed the crimes they are accused of.
