fix(status-page): replace multi-line awk with shell loop for ash compatibility

Browse source 
The TIER_JSON generator used a multi-line awk script embedded in a
\$() command substitution with escaped double quotes inside a
single-quoted awk program. Alpine's ash shell refused to parse this,
reporting "syntax error: unterminated quoted string". Under set -e
the syntax error killed the script BEFORE the jq call that writes
status.json, so the file stopped updating after our monitoring changes
triggered a full re-parse cycle.

Replace the awk block with a portable while-read shell loop that ash
handles cleanly. Verified with both `bash -n` and `alpine:3.20 sh -n`.
