PER-10480: Enable re-import

[cecilia-donnelly]

Allow a member to re-import a previously imported family member from FamilySearch. This is not the same as sync because we re-create the archive on re-import, so @omnignorant asked me to add a confirmation step that explains that a new archive will be created.

Showing this on Loom since this integration is hard to test: https://www.loom.com/share/bdb6b0e2c2bf4088af8d65529295759c

(Ignore messy git nonsense, I accidentally clicked the "merge main into this branch" button and I am going to fix it up after Copilot reviews.)

This works, let's ship it.
