CanbiZ (MickLesk) 75c0b1bfc9 fix(error-handler): prevent silent() from re-enabling error handling during recovery
Root cause: silent() (core.func) unconditionally calls set -Eeuo pipefail
and trap 'error_handler' ERR after every command. When build_container()
intentionally disables error handling for its recovery section, any
intermediate call through silent()/ re-enables it. This causes the
grep/sed pipeline for missing_cmd extraction to trigger error_handler
(grep returns exit code 1 on no match + pipefail = fatal).

Fixes:
1. silent(): Save errexit state before disabling, only restore if it was
   active. Callers that intentionally disabled error handling (e.g.
   build_container recovery) are no longer silently re-enabled.

2. build.func: Add || true to missing_cmd grep pipeline as defense-in-depth
   against pipeline failure propagation.

3. build.func: Add explicit set +Eeuo pipefail / trap - ERR after
   post_update_to_api() call, before error classification grep/sed section.

4. build.func: Remove stale global combined_log variable from variables()
   that used a different path format (/tmp/install-SESSION-combined.log)
   than the actual local variable (/tmp/NSAPP-CTID-SESSION.log). The global
   was never written to and caused confusion when error_handler displayed it.
