librelad 6813621fe9 config: enable multiple instances everywhere it is actually possible
Three apps were instanceable and the rest were silent, so the feature
looked far narrower than it is. Every app has now been checked against
the two rules instance_create.sh enforces, and the answer recorded in
its config rather than left unset.

32 apps are instance-safe and now say so. Six are not, and each says why
in its own words instead of being indistinguishable from an app nobody
had reviewed:

  pihole      a DNS server must own port 53
  unbound     a resolver must own its fixed 5335
  stalwart    a mail server must own 25/465/587/993
  traefik     must own 443, and one Traefik routes every other app
  prometheus  node-exporter and cadvisor carry no "prometheus" prefix
  stoat       pins 7881, and database/redis/rabbit/minio carry no prefix

The first four are genuinely one-per-host: the port is not arbitrary, it
is the protocol. The last two are compose-identity problems and could be
fixed by prefixing those service names, which is a change to make
deliberately rather than in passing.

Recorded as an explicit false with a reason, not left unset, so the next
person reads a decision instead of an absence. The audit was verified not
to pass anything vacuously: every app resolves at least one service name,
so no app reached "eligible" merely because nothing was found to check.

# SECRETS
# =============================================================================
# These feed the compose via #LIBREPORTAL|MASTODON_<KEY>_TAG| tags. They are
# auto-generated on first install and — unlike a generator tag in the compose —
# preserved across reinstalls, which is what keeps them in step with the
# Postgres volume and with every logged-in session.
#
# DB_NAME / DB_USER / DB_PASSWORD = Postgres database, role and password. Set
# once by initdb when the volume is created; changing them afterwards without
# also changing them in Postgres locks Mastodon out of its own database.
# SECRET_KEY_BASE = signs and encrypts Rails session cookies. Rotating it logs
# every user out.
# OTP_SECRET = protects stored two-factor enrolments. Rotating it invalidates
# them, and anyone with 2FA on needs it reset before they can log in.
# VAPID_PRIVATE_KEY / VAPID_PUBLIC_KEY = Web Push identity. These two are the
# halves of one P-256 keypair, so they cannot be generated independently the
# way the other secrets are — mastodon_install_post_setup replaces the pair
# below with a real one on first install, and never touches it again.
# RANDOMIZEDVAPID<n> is kept here only so the tag always has something
# substitutable: if key generation ever fails, Mastodon starts with push
# broken rather than with a literal placeholder as its key.
