modmail: constantify user ID and fix bug where users can bypass modmail route checks

Browse source 
the random c.sentto == 2 magic numbers in the code is... pretty
unmaintainable and unless you were aware of who "2" was, it's hard to
know what's going on.

in addition, we force modmail to go through the modmail path instead of
letting users bypass validation checks.
