Rename targets, route messages to debug console, clean up

- Rename CMake project and library target to BobinkQtOpcUa (URI stays Bobink)
- Rename demo target to BobinkDemo, output binary to build/bin/
- Route all QML status/error messages to the in-app debug console
- Remove discoveryInterval QML property, default to 30s internally
- Add errorChanged handler, PKI file validation in applyPki()
