* Clean the user's display name on update.
The user's display name should always be clean (see for example
functions/src/create-user.ts). However, change-user-info.ts does not
enforce this, thus potentially allowing a malicious user to change their
name to something that doesn't satisfy the rules for clean display
names.
Note: this cannot happen currently because all callers (in profile.tsx)
clean the name. However, doing it here is good defense in depth
(similar to how the userName is cleaned).
* Update display name max length to 30
* Add a script to hunt down too-long display names
* Make util.isProd a function
* Don't access admin.firestore() on top level of utils.ts
