Certificate Key Store/Generator to make HTTPS GUI a default

AdGuard Home is becoming more popular with non-IT people who want to use it for private home network, but they don't like SSH. It looks complicated to them. AdGuard Home already includes most common/typical features in its GUI, but requires use of SSH and/r use of 3rd party tools for:
- Resetting all settings to default (requires SSH to remove AdGuardHome.yaml)
- Password reset (requires SSH login to edit AdGuardHome.yaml and requires BCrypt generator)
- Generating self-signed SSL certificates to use HTTPS for login screen as default (requires use of 3rd party tools to generate SSL certificates)

I think routers use certificate key stores to generate unique self-signed SSL certificates, similar to how unique default SSH keys are re-generated on devices like Raspberry Pi.
