fix(gui_2,app_controller): two regressions blocking uv run sloppy.py

1. gui_2.py:_gui_func — ws was only assigned inside 'if bg_shader_enabled'
   (default False), but used unconditionally on the next line. When the
   shader feature was off, theme.render_post_fx(ws.x, ws.y, ...) raised
   UnboundLocalError, which immapp.run caught and degraded the app.
   This is what was blocking the GUI from appearing.

   Fix: hoist 'ws = imgui.get_io().display_size' above the conditional
   so it's always assigned. The 'if bg_shader_enabled' branch now uses
   the already-assigned ws.

2. app_controller.py:_push_mma_state_update_result — production code did
   'Ticket(id=t.id, ...)' on each element of self.active_tickets, but
   the test sets self.active_tickets to a list of dicts (mock data).
   Production callers go through _load_active_tickets which converts,
   but mock callers bypass. Added 'Ticket.from_dict(t) if isinstance(t, dict)
   else t' normalization at the entry point (same pattern as line 3295).

After these fixes:
- live_gui_health_endpoint returns healthy=True
- test_push_mma_state_update passes
- test_api_hooks_gui_health_live passes
