Chore(webapp): Adds additional billing alerts (#2829)

- Adds 4 additional alert thresholds to ensure customers are emailed if
they have runaway usage.
- Separated these into a new section called "Spike alerts" with a
tooltip so it's clear what they are.
- Tooltip message is: "Catch runaway usage from bugs or errors. We
recommend keeping these enabled as a safety net."
- A billing service PR now returns all orgs to populate the email list,
rather than oldest 5.
- Adds `defaultChecked` logic to honour existing orgs who have
configured alerts in the DB. New orgs get all alerts checked on by
default.
