### Context
Some of our users' emails were getting stuck in sending. The long delays
in processing the retries caused a vercel function timeout.
### Summary of Changes
We refactor the low level email sending functions to remove the retry
logic there. We kick it up to the email queue step. Additionally, we
flag emails to be retried when they encounter issues but leave it for a
future iteration to actually perform the retry. We perform an
exponential backoff with a random component to decide when they have to
be retried. We also make some small adjustments to the queuing function
to not queue skipped emails.
When an email fails to send during the sending function, we check to see
if it is a retryable error or not. Some errors are transient and trying
again may succeed while others indicate deeper issues. If it is
retryable, and the max number of retry attempts hasn't been reached, we
set `nextSendRetryAt` to a time determined by an exponential backoff
calculation function. When the queuing function looks for emails to
queue, it doesn't just pick up the `SCHEDULED`. emails whose
`scheduledAt` time <= `NOW()`, but also those emails whose
`nextSendRetryAt` time <= `NOW()`. What this means in practice is that
one iteration of the `email-queue-step` will mark emails as retryable
while another iteration will perform the retry. This should be cleaner
and prevent long delays in the `email-queue-step` process due to
retries. This also makes it easier to scale up the number of retries if
need be.

## Summary by CodeRabbit
* **Bug Fixes**
* Improved pricing accuracy by implementing proper rounding in unit
price calculations during checkout. This ensures correct cent-level
precision in purchase computations, preventing potential rounding errors
in transaction totals.

### Context
A small amount of email monitor requests take slightly less than 3
minutes to complete. This meant our old timeout of 2 minutes was
flagging a few kuma pulls as "down" when they weren't.
### Summary of Changes
We just bumped the timeout. This should be ok in prod because the uptime
kuma timeout is set to 200 seconds.
