Explicitly exempts admin action routes from rate limiting because
the limits were being hit during normal user behavior.
While verbose, alternatives like grouping admin routes into e.g. a
Flask blueprint to modify their behavior as a collective would have
been a larger refactor than seemed wise at the moment.
Also, some routes that were limited at 1/second were originally set
as such as a makeshift debounce for people double-clicking buttons.
This was discussed and deemed an acceptable risk compared to making
the mod queue more frustrating to go through.
Due to use of Submission.{choices, options, bet_options} in realbody,
generating submission_listings resulted in extremely high volume of
SELECT queries.
In local testing with 6 posts, one of which had a poll with 2 options,
the removal of these calls reduced quantity of queries on the homepage
from 84 to 22.
Given that it was previously decided to remove the polls feature after
a regression while adding comment filtering, the remaining dead code
paths for polls were also removed.
Ports in lightly modified logic from the upstream which tracks active
sessions to provide counters and listings to understand site traffic
in the admin panel.
