Return 404 instead of 400 when no accounts breached.

Trim spaces from admin token during authentication and validate that the admin panel token is not empty

Added newlines to config options to keep them a reasonable length.

Print a warning when an env variable is being overriden by the config file, and reorganize the main file a bit.
Modified the JWT key generation, now it should also show the output of OpenSSL in the logs.

Removed list of mounted routes at startup by default, with option to add it back. This would get annoying when starting the server frequently, because it printed ~130 lines of mostly useless info
