Features big update

[vncloudsco]

Your software is great, we see there are still many problems, so we have developed and optimized a series of features and implementations:

• Make the homepage more useful
• Get better information from the node about the CPU level, RAM in use
• Better synchronization mechanism when adding nodes, nodes lose connection to limit system crashes when nodes are down, have detailed statistics on node status
• Support for Vietnamese
• Deploy with python venv to ensure speed and avoid system conflicts
• Support using API through API key statics to help the connection process minimize the number of requests sent to the system, thereby reducing the load on the system.

Thanks for your review, however I noticed that too many files are outdated when they should be reviewed before other updates are reviewed. I also can't see how they conflict. If you can, please help me fix it. If not, we will close the request.
