Out of memory issues when accessing admin

[scarroll32]

Multiple changes made:

• updated Active Admin
• Updated Sidekiq
• Changed workers = 1
• Removed font awesome from Active Admin
• Removed Auth Trail (again)
• Removed Prometheus endpoint
• Removed references to notebooks in Articles

Status

• All is working except for Active Admin fonts.

The latest release of Active Admin seems to be the main issue, but it has been updated due to a GitHub security warning. Probably a good idea to replace it with a hand-rolled admin.
