Settings dump now retains every key from the Settings table and replaces
sensitive values with [REDACTED] instead of dropping the row. New config
flags automatically surface in future bundles without a code change.
Adds integrations.spoolbuddy with per-device firmware, NFC/scale hardware,
calibration, online state and uptime — anonymized (no hostnames, IPs or
device IDs). Both /support/bundle and the bug-report bubble benefit, since
they share _collect_support_info().
