Update OAuth2 property names to camelCase

 This commit updates the OAuth2 property names to use camelCase instead of snake_case to maintain consistency with JavaScript naming conventions. The changes include updating the property names in the
 HTML, JSON locale files, and the JavaScript backend code. The affected properties are `grant_type`, `access_token_url`, `authorization_endpoint`, `redirect_uri`, `open_authentication`, `client_id`,
 `client_secret`, and `client_credentials_in_body`, which have been changed to `grantType`, `accessTokenUrl`, `authorizationEndpoint`, `redirectUri`, `openAuthentication`, `clientId`, `clientSecret`, and
 `clientCredentialsInBody`, respectively. Additionally, the commit includes updates to the corresponding labels and placeholders in the UI components.
