refactor webview auth default region setting, move from LastLoginIdclnfo constructor to callee(webview browsers)

Will-ShaoHua commented 3 months ago

As a new ToolkitAuthManagerState will be created every few mins by the IDE to sync, thus the same warning log entry will pop up accordingly and spam the log file

data class ToolkitAuthManagerState(
    // TODO: can't figure out how to make deserializer work with polymorphic types
    var ssoProfiles: List<ManagedSsoProfile> = emptyList(),
    var lastLoginIdcInfo: LastLoginIdcInfo = LastLoginIdcInfo()
)

data class LastLoginIdcInfo(
    var profileName: String = "",
    var startUrl: String = "",
    var region: String = AwsRegionProvider.getInstance().defaultRegion().id
)
