[Feature](database): Add Support for SSL Connections and Database URL Configuration (#2540)

* feat(database): add support for SSL connections and database URL configuration

* feat(config): update Redis configuration to use TLS in configurre name instead of SSL

* fix(database): remove default values for DatabaseURL and SSLMode in DatabaseConfig

* chore(.gitignore): add cloudreve built binary to ignore list
