force QEDaemon singleton, and refer to QEDaemon.instance where possible
In cases where we would run into circular dependencies, pass the instance
also refer to singleton QEConfig instead of passing instance in qeapp.py

TypeError: arguments did not match any overloaded call:
setFocus(self): too many arguments
setFocus(self, reason: Qt.FocusReason): argument 1 has unexpected type 'int'
Some functions have an argument named "seed_type" in which it was annoying to call the seed_type() fn.

pyinstaller tries to import electrum and its different submodules at build-time
during the "Analysis" phase. sys._GUI_QT_VERSION was not getting set there,
and the resulting exception was blocking pyinstaller from discovering that
gui/common_qt is being used.
at runtime:
