Improve Unicode support, emojis don't crash us anymore lol!

Browse source 
A few pieces here:

1. Convert all tables to `utf8mb4`+`utf8mb4_unicode_520_ci` strings.
2. Configure that as the server's default.
3. Configure the Rails database connection to use this encoding too.

Came together pretty well, whew! This has been a LONG time coming,
`latin1` is NOT a good charset for the year 2024!
