IA Correction - Usability enhancements to People and Roles table

Scott identified a number of usability issues with the 'undo' button

Visual/UX Design Ticket:
https://app.zenhub.com/workspaces/entity-5bf2f2164b5806bc2bf60531/issues/bcgov/entity/5124

1) ~selecting correct should display the form inline in the row in the P&R table~ **handled by #5076**
2) when person or corporation is added to the P&R table, the default action button should be "edit" and the dropdown option should be "Remove". Button is "Edit" not "Correct" in this case.
3) Drop-down alignment - the "Remove" button in the segmented button should be right aligned with the drop-down arrow. *(Also add to IA)*
4) Change Alert Text - Change "Add role" alert to "Missing Role"; ensure colours match the Invision comp. *(Also add to IA)*
**Edit UI handled by #5076**
5) ~Ensure only one completing party is displayed in the People and Roles table (whether added via the Add Person button or the Add a Completing Party button). Test when a pre-existing Completing Party is removed, a new Completing Party is added via the "Add Completing Party" button, and the original Completing Party is restored via an "Undo".~ **fixed by #5076**

- ~When you have an added a NEW person, the primary action should be "edit" and the dropdown action should be "remove".~ same as # 2 above

6) In the case when you are about to correct a person, the primary action should be "correct" and the dropdown action should be "remove".
7) When the person has been corrected, it should show a segmented button with primary action: "undo", dropdown would include "correct" and "remove"

Review the People and Roles table and the linked Visual/UX Design ticket (ZenHub issue 5124), separating items already handled by #5076 from the remaining work. Done means items 2–4, 6, and 7 match the specified primary and dropdown actions, alignment, alert wording, and colours.
