Alt+drag: validate WINGs fb hit via context_find 

When handle_pointer_button finds a client surface at the pointer (_surf && _tv),
it searches frame_list for overlapping WINGs frame_bufs. Previously it used
any WINGs fb found, including stale entries with bogus IDs (e.g. 0x1).
Now it validates the WINGs fb via context_find() before using it as the
event window. If validation fails, the event routes to _tv->id.
