fix(box): routine bravo without full-screen layer

Browse Source 
The end-of-routine "Bravo !" screen wedged the LVGL render task
(task_wdt loop) on this RAM-tight box. Root cause via decoded
backtrace: LV_SCR_LOAD_ANIM_FADE_IN applies opacity to the whole
screen and the star's transform_scale animation both force a
320x240 intermediate layer that the 16-line flush buffer cannot
allocate, hanging lv_draw_layer_alloc_buf.

Use a MOVE_LEFT slide like every other screen and a static star.
