fix(telemetry): prevent stuck 'installing' status in error_handler.func

The catch_errors() function in CT scripts overrides the API telemetry
traps set by build.func. This caused on_exit, on_interrupt, and
on_terminate to never call post_update_to_api, leaving telemetry
records permanently stuck on 'installing'.

Changes:
- on_exit: Report orphaned 'installing' records on ANY exit where
  post_to_api was called but post_update_to_api was not
- on_interrupt: Call post_update_to_api('failed', '130') before exit
- on_terminate: Call post_update_to_api('failed', '143') before exit

All calls are guarded by POST_UPDATE_DONE flag to prevent duplicates.
