[Feature Request] Improvements to API Endpoints

[nolrinale]

To improve the bookeeping capabilities of newserv it can also retrieve:

• Account Creation Date
• Account Last Access Date
• Teams Information (for BB)

And be able to record in a small persistent json file and retrieve:

• Total Monsters defeated (maybe by difficulty, quest, maps , etc?)
• Total Rare Items dropped (by monster name, from boxes?)
• Challenge Mode (date, party name, ranks, times, party members)
• Battle Mode (date, party name, results, party members)

Or just directly send all these live data in a socket endpoint like the rare drop notif one? then the user can decide how they want to save or treat this data
