fixes https://github.com/TryGhost/Product/issues/3738https://www.notion.so/ghost/Member-Session-Invalidation-13254316f2244c34bcbc65c101eb5cc4
- Adds the transient_id column to the members table. This defaults to
email, to keep it backwards compatible (not logging out all existing
sessions)
- Instead of using the email in the cookies, we now use the transient_id
- Updating the transient_id means invalidating all sessions of a member
- Adds an endpoint to the admin api to log out a member from all devices
- Added the `all` body property to the DELETE session endpoint in the
members API. Setting it to true will sign a member out from all devices.
- Adds a UI button in Admin to sign a member out from all devices
- Portal 'sign out of all devices' will not be added for now
Related changes (added because these areas were affected by the code
changes):
- Adds a serializer to member events / activity feed endpoints - all
member fields were returned here, so the transient_id would also be
returned - which is not needed and bloats the API response size
(`transient_id` is not a secret because the cookies are signed)
- Removed `loadMemberSession` from public settings browse (not used
anymore + bad pattern)
Performance tests on site with 50.000 members (on Macbook M1 Pro):
- Migrate: 6s (adding column 4s, setting to email is 1s, dropping
nullable: 1s)
- Rollback: 2s
