5a3664aee2 Add support for caching slow queries on large databases.
- Add materialized views for list -> subscriber counts, dashboard chart,
  and dashboard aggregate stats that slow down significantly on large
  databases (with millions or tens of millions of subscribers). These
  slow queries involve full table scan COUNTS().

- Add a toggle to enable caching slow results in Settings -> Performance.

- Add support for setting a cron string that crons and periodically
  refreshes aggregated stats in materialized views.

Closes #1019.

a1aeba22bb Fix invalid link click registrations
The link_clicks.link_id table was NULLable incorrectly. Links that
do not exist should not register a tracking entry. Fix the query
and also update the schema + migration (breaking table change).
