Updated deps and misc fixes and updates

- Updated some Rust dependencies
- Fixed an issue with CSP header, this was not configured correctly
- Prevent sending CSP and Frame headers for the MFA connector.html files.
  Else some clients will fail to handle these protocols.
- Add `unsafe-inline` for `script-src` only to the CSP for the Admin Interface
- Updated JavaScript and CSS files for the Admin interface
- Changed the layout for showing overridden settings, better visible now.
- Made the version check cachable to prevent hitting the Github API rate limits
- Hide the `database_url` as if it is a password in the Admin Interface
  Else for MariaDB/MySQL or PostgreSQL this was plain text.
- Fixed an issue that pressing enter on the SMTP Test would save the config.
  resolves #2542
- Prevent user names larger then 50 characters
  resolves #2419
