in short, the `/report` endpoint now checks if:
- the reporting room in the URI matches the PDU/event reported
- sender user is in the room reported
- raises report reasoning to 750 characters (spec doesn't say to limit
these, but thorough and informative reports for server admins are not
a bad thing)
- (hopefully) fixes some broken formatting
- add a random short delay before sending a successful response to the
client to make it more annoying to enumerate for events on our server
(security by obscurity but spec suggests it)
basically, secure reports better lol

this seems to require some more work to properly ignore
dead server errors without breaking the entire room join

amazing that this wasn't done in the first place. a lack of a UA is
suspicious and some providers may block our requests just for the sake
of no UA.
