Subject: [PATCH] Activations: add an enabled_at column

For #1140, I considered trying to use the existing fields in a better
way, but because we already use the activations table to store
preferences, we need to keep all of the existing data and its usage
as-is.

The enterprise code will use this new column to decide how long the
trial period should be.
