Current known issues

• When starting up the web locally, the discord bot often cannot start fast enough, which leads to an error when serving the page to the user (e.g. DiscordClient.GetUser(id) returns null
• The donut graph on the Stats and User Lookup pages does not show information in the same way that the vue version does
  • This is a limitation of MudBlazor, there are other libraries available for this purpose but I have not checked them out
• I've tried my best in making it look OK on mobile, but there is still room for improvement
• The markdown library used seems to have issues editing codeblocks (the page becomes unresponsive)

TODO

• Discuss and/or decide on whether or not the structure I've decided to go with here is something we want to change
• Themes? I have currently skipped implementing this
