fix migration scripts for non-interactive SSH and bash 5.3

01-fetch-events.sh: nak buffers output when stdout is not a TTY, causing
it to hang silently in non-interactive SSH sessions. Wrap with 'script'
to provide a pseudo-TTY, then strip the injected carriage returns and
connection banner line from the output.

40-classify-actions.sh: bash 5.3 treats ${#assoc[@]} and array iteration
as unbound variable errors under set -u when arrays are empty. Replace
${#assoc[@]} with explicit counters and guard array iterations with
set +u/set -u.
