fix(appd): kill file portal process on all early-return paths in supervise()

Browse source 
Runtime spawn failure, READY timeout, and abort-during-startup all
previously returned without killing the portal child process or removing
its socket file. Extracted kill_portal() to consolidate cleanup and
call it in each of those three paths.
