fix: improve error trace propagation for telemetry

Browse Source 
- post_update_to_api: Attempts 2/3 now send medium_error (16KB truncated
  log) instead of short_error (generic description only). This is the
  primary fix — when attempt 1 fails (120KB payload too large/timeout),
  attempts 2/3 no longer discard all log data.

- _send_abort_telemetry: Increased container fallback from 20 to 200
  log lines (capped at 16KB). Added SILENT_LOGFILE as fallback source.
  Added exit code explanation header and error_category to payload.

- get_error_text/get_full_log: Added SILENT_LOGFILE as last-resort
  fallback when INSTALL_LOG, combined log, and BUILD_LOG are all
  empty/missing.
