feat: Adds some QoL changes

- Logs exception messages when Plex login fails
 - Renames "username" variable in getPlex() to generic naming
 - Changes "roles" config to "plex_roles" in preparation for jellyfin
 integration
 - Changes generic config names to plex specific config name

task: none (because I'm too lazy to set up proper issues)
