Five apps (mastodon, owncloud, mattermost, matrix, stoat) took their generated
secrets from the compose-side generator tags PASSWORD_TAG_<n>/RANDOM_TAG_<n>/
HEX_TAG_<n>/VAPID_TAG_<n>. Those mint a fresh secret on every templating run, so
a reinstall handed the app a new database password while its data volume kept the
one initdb was given, and the app came back up unable to open its own database.
Move them to <app>.config as RANDOMIZED* placeholders, reaching the compose via
the #LIBREPORTAL|<APP>_<KEY>_TAG| mechanism tags_processor_app_config_values
already provides. No new handler: the tag name is derived from the config key, so
this is a config line plus a tag per secret. Generation is unchanged — still
random on first install; the value is now remembered instead of re-rolled.
Also fixes two things this exposed:
- The RANDOMIZED* replacers matched unanchored. `sort -u` orders slots lexically
(1, 10, 11, 2), so slot 1's pattern rewrote the prefix inside slot 10's
placeholder and slots 10+ ended up holding slot 1's secret with a digit glued
on — derivable, and invisible because the values weren't byte-identical.
Anchoring with \b makes match order irrelevant. Verified at 20 slots across
all four placeholder types: 64 keys, 64 distinct values, no prefix collisions.
- generateRandomPassword drew from base64 without constraining the mix; measured
over 2000 draws, 1 in 40 contained no digit at all. Retry until the result has
both a digit and a letter, bounded so a pathological length can't spin.
owncloud gains a fix in passing: its compose seeded the admin account from
PASSWORD_TAG_2 while the WebUI displayed CFG_OWNCLOUD_ADMIN_PASSWORD, which was
generated separately and never used. Both now read the same value.

One container against Postgres, with the polished desktop and mobile clients
that make it the least demanding of the four chat options.
Runs as the bind-mount owner via USER_TAG: the image bakes in USER mattermost
(uid 2000) so it never runs as root and cannot chown its own data directory,
which under rootless Docker means it dies on first write.
CFG_MATTERMOST_AUTHELIA stays false — OIDC/SAML is a paid tier here, so
forward-auth would block the native clients from the API without buying single
sign-on in exchange.
