Encrypt email addresses / names

[ferrisoxide]

Describe the task

Encrypt email addresses and names, using Rails's Active Record Encryption.

NB We will want to use deterministic encryption, as we still need to look up users by name / email address.

Success Criteria

• MUST encrypt user email addresses
• MUST encrypt user names
• MUST allow admins to search for users by email address or partial name

Additional Notes

Might be worth looking at integrating Ransack first, and then figuring out how to look up partial names (e.g. load into memory and filter)
