Add new method to create account from user instead of just email, so
type is preserved

This is so we can filter by account type later in the process
I could filter here, in getting accounts from users, but that
restricts the number of available sessions

This way I can filter when returning availableSessions, giving
priority to pro users but falling back to basic user accounts if
needed

We have at least one reported instance of a meeting being created
with an account that was already in use
There is not enough data to debug how or why this happened
In the unlikely but I guess technically feasible event that this was
caused by the user starting a meeting Just after the live meetings
check had been made, this change would improve chances of avoiding
the problem happening again

Add missing closing paran to accountMeetings Array from line
Move question mark in Account type optional param definition

Prvious commits were all made with prettier disabled, because I had
not yet figured out what syntax error was breaking linting

The commit with the syntax error fixes is easier to read without also
including all the linting, so I disabled prettier on that commit as
well

Thus, the linting for the last few commits all in one swell foop

As a warning to future us, if we scale to having more than 30 zoom
user accounts

Note that there is a time limit, and offer workarounds

Inform them instead of annoying them... hopefully

This is replaced by accountFromUser
Also make Account type param mandatory
