rCOMM97cea65d1b74: [server] Always filter message queries by message creation time

Summary

This solves ENG-812: Improve perf of website load. By limiting the amount of messages that MySQL has to look at in order to resolve fetchMessageInfos, we speed up website load significantly.

On my local environment using the prod database, the query resolves in 0.5s instead of 20s.

Depends On D3348

Test Plan

I downloaded the prod database to my local machine and tested how long the query to load the website took. This change reduced it from 20s to 0.5s

I realized I should probably gate this behind a hasMinCodeVersion given native needs D3350, D3352, and D3353 to work properly with this change. Just put up D3354 to gate the changes

471	q: Could you add a comment here with the normalized amount of time here? I'm assuming it's two weeks at a glance but wasn't 100%. Also, might just be me but it feels odd that there's a time value in `message-types`
