ci(ruff): add bandit checks (#575)

Added bandit checks to continuous integration.

Updated sources to pass bandit checks:
- replaced asserts
- added timeouts to requests
- added checks for process command execution
- changed to 127.0.0.1 as default IP address for EOS and EOSdash for security reasons

Added a rudimentary check for outdated config files.

BREAKING CHANGE: Default IP address for EOS and EOSdash changed to 127.0.0.1
