Marketing SMS dispatch: Save to DB on error

We were losing error information.

---

Fix signup agreement div click issue

Clicking the div would update the React state,
but not the React Hook Form state, which works based on the native
input state, which isn't changing with React's rendering.

This uses refs to keep things in sync, and drives the state
from the checkbox rather than higher up state
created through React.useState.

---

Convert some FKs to ON DELETE CASCADE

Found while working on the release fixup,
these should logically already be CASCADE.

---

Support secure restores to staging

This adds a new rake task that can be used to restore a production dump
to a staging database, removing all non-admin member data.

This ensures that even if someone makes it to staging or
somehow grabs a copy of the DB, no member data is included.

---

Rename prepare_prod_db_for_testing

It's only valid for local dev, since it contains potentially
sensitive data; it should not be used in places like staging.

---

Analytics: Add charge.incurred_at

We need to know when the charge was incurred by the user,
not when Suma processed it, for example if we have to do
a historical import.
