Fix PSI access threading issues in CsvTableModelSwing

[coleleavitt]

getColumnName(int column)

now wraps all PSI access in

 ApplicationManager.getApplication().runReadAction

This ensures that reading PSI elements occurs safely within the required read action context, fixing runtime errors about improper thread access.
resolves exceptions like: Read access is allowed from inside read-action only

log:

com.intellij.openapi.diagnostic.RuntimeExceptionWithAttachments: Read access is allowed from inside read-action only (see Application.runReadAction()); If you access or modify model on EDT consider wrapping your code in WriteIntentReadAction ; see https://jb.gg/ij-platform-threading for details
