actop 1.9.11

Fixed

• Every single-letter keybinding was dead on startup (l, g, c, p, s,
  t, q). The hidden #filter-input was auto-focused on mount and silently
  swallowed the keys: pressing l typed an l into an invisible regex box
  instead of cycling the layout preset. Textual's default screen AUTO_FOCUS
  ("*") focuses the first focusable widget, and display = False does not
  make a widget unfocusable — visible tracks the visibility style, not
  display — so the invisible input was a legitimate focus candidate and won.
  ActopApp now sets AUTO_FOCUS = None and assigns focus explicitly
  (_focus_default_widget(): the process table when shown, else the
  non-focusable dashboard), so the letter bindings are live from the first frame
  and the process table gets the arrow keys when it is visible.
  The TUI tests had been papering over this with app.set_focus(None), blaming
  the headless harness for what was a real production bug; those workarounds are
  removed so the tests now fail if focus regresses.
