Add support for MTLs auth

[WoodardDigital]

Hello,

I did some work this afternoon to add the ability for myself to be able to use MTLs auth with the certs that my company uses, I'm able to specify the local files for connecting to my instance.

I validated that connection to other instances was also successful (Only open though, I don't have another instance that uses Bearer or username\password at this time)

How to configure.

1. Select "Mutual TLS" under "Authentication Type" in the settings.
2. Fill in paths for your respective certificate files on your local computer
3. Set priority for account search
4. Test and save

Disclosure I wanted to zip through this, so I did use GPT to help with debugging a bit when I ran into issues. I've got most if not all of the artifacting of that removed.

This has NOT been tested on a mobile device.
