feat: dynamic protection, easy cert swap, auto save settings...

[castdrian]

this pr aimes to resolve quite few more qol issues that were raised in the repo/discussed privately

• remove remaining unusernotification stuff
• ignore all cpp source and header generated warnings in xcode since they're part of subprojects
• resolve all deprecation warnings and all other remaining warnings (except uibutton contentinsets)
• implement dynamic ppqcheck protection setting which in turn resolves Add button when signing to toggle on/off PPQprotections #141
• resolve Select certificate through signing options #185
• resolve Add direct install support #187
• signing settings auto save now (will revert if you don't like, but found it quite annoying, frequently forgot to save and wondered why stuff isn't working)

there was a teeny tiny mismatch with the switches and their settings, fixed and added some logging to prevent this from happening in the future
