RoE µUpdate for Merits + timed messages

[Kreidos]

Microupdate adds the messages for new Timed Record blocks at login/JST-midnight as well as allowing chars at max level in Merit Mode to accumulate progress for the Gain EXP timed record.

I affirm:

• [x] that I agree to Project Topaz's Limited Contributor License Agreement, as written on this date
• [x] that I've tested my code since the last commit in the PR, and will test after any later commits
