closes https://github.com/TryGhost/Ghost/issues/12461
Design changes:
- added activity feed to member details page
- rearranged Stripe info to display on the right
- added toggle buttons for Stripe subscription and customer info
- added box to display activity feed for received and opened emails
Functionality changes:
- added `queryRecord()` to member adapter so `queryRecord('member', {id: x})` will hit `/members/:id/?query` instead of `/members/?id=x&query`
- updated member route to query member with `?include=email_recipients`
- added `EmailRecipient` model for access to event timestamps and email relationship setup
- added `<GhMemberActivityFeed>` component that accepts an `EmailRecipient` array and converts that into an activity list
- added support for `@model=emailInstance` to the email preview modal
- fixed a timing issue with email preview that could result in it showing blank content until the mobile/desktop toggle is used
- fixed sometimes blank member location
