refactor: process picker themed styling, context menu, auto-select

Browse Source 
Extract shared init into initUi(). Apply dark theme styling from global
palette to table, header, filter, and buttons. Add right-click context
menu with Copy PID/Name/Path. Auto-select last attached process on open.
Remove duplicate attach->accept() connection from .ui (handled in code).
