In the past you've applied to extend your stay in the UK, to the extent that you invoked a court case under article 8 of the European Convention on Human Rights. This has marked you as someone very keen to stay in the UK, and thus at a high risk of going underground if you're allowed to visit again. I'd be very surprised if you can get a visa in the next few years.
What you should do is clear: consult a lawyer with expertise in UK immigration.
This may seem an abrupt answer but your case is far too complex for strangers on the internet to be able to contribute meaningfully.
Good luck!
