[TTAHUB-160] final changes to export message from accessibility spec. and lowering limit

[thewatermethod]

Description of change

Changes to the "over-the-limit" export menu

• Out of accessibility review, we rethought having a disabled button at all, since the user experience for a disabled control like that can be quite poor. Instead of disabling the button, we remove it. In order to give additional context to the menu's functionality that the button was previously providing, we change the dropdown from "Reports" to "Export reports"
• Removed ellipsis on those menu actions, also as per UI/accessibility review
• Reports from users indicate that 5000 might be too high of a limit. We have lowered it to 4000.

How to test

Attempt to export more than 5000 reports. Confirm that the error message appears, and the button does not. Attempt to export less and confirm it works as normal.

I would double check the max supported at standup/office hours and try to get it lower. I imagine we will still hit a lot of errors with the limit at 4k
