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.

The tag manager reads `#LIBREPORTAL|<TAG>|<VALUE>` and takes <VALUE> as the
current literal to search for on that line, so it must equal the string in the
line body. Mastodon used `unconfigured` as the annotation value against bodies
like `PASSWORD_TAG_1_DATA` — nothing matched, nothing was ever substituted, and
the placeholder shipped as the live database password, SECRET_KEY_BASE, OTP
secret and VAPID keypair.
Nothing caught it either: `unconfigured` doesn't match `_DATA`, so
tagsManagerGetTagState reported the tags as configured, and the stale-tag gate
in dockerComposeUp (which tests the annotation value against
`^[A-Z][A-Z0-9_]*_DATA(_[0-9]+)?$`) let the app start.
Adopt the convention every other app already uses — body placeholder identical
to the annotation value, `<KIND>_DATA_<n>`. All 11 tags now substitute, the app
and postgres services agree on the same generated credentials, and an unfilled
tag is visible to the pre-start gate.
Existing 0.1.0 installs keep their literal credentials until re-installed, and
their Postgres was initialised with them, so a plain re-install desynchronises
the compose from the volume. Document both recovery paths in upgrade notes.
