refactor: split MainWindow constructor into focused setup methods

Browse Source 
Extract the ~300-line constructor body into setupDocks(), setupScrobbler(),
setupGapless(), setupMpris(), connectBackendSignals(), connectLibrarySignals(),
connectContentSignals(), and connectToolbarSignals(). No behavioral changes;
all signal/slot connections and widget creation remain identical.
