fix: update Jitsi configuration handling for default values

- Refactored the Jitsi configuration logic to use nullish coalescing for default values in the frontend.
- Added a condition to reset configuration values to defaults when no configuration is available.
- Adjusted backend mutation to ensure consistent handling of the acceptSelfSignedCert parameter.
