Adds the two Dockerfiles nextcloud's compose build: contexts were
already referencing but never had (custom smbclient support for the
main container, a documentserver base for euro-office) - both had
their real internal-CA-trust mechanism replaced with a comment
explaining what's there and why, per the standing rule against
publishing that detail.
Also fixes a compose bug: kodi-ma-bridge's `environment:` key had
been dropped, leaving KEY=value pairs nested under `env_file:` (which
expects file paths, not inline vars) - would have made docker-compose
try to open a file literally named `TZ=${TZ}`.
Rest of this commit is manual cleanup (comment tidying, dropped
personal media-library volume mounts, a couple of .env comment
trims).
Adds real Vault Agent secret templates and non-secret env vars for
14 platform stacks (caddy, caddy-internal, dashy, docker-socket-
proxy, dockhand, gitea, grafana-stack, hawser, kestra, kopia,
mosquitto, nocodb, node-red, speedtest-tracker), sanitized per the
kv/host/... convention established for identity-and-security.
Also fixes 6 variable-name mismatches discovered while cross-checking
every new .env/.ctmpl against what its actual public compose file
references (the public compose files were already adapted from the
private originals during an earlier reorg pass, so names don't always
match 1:1): authentik (PG_USER/PG_DB/PG_PASS), gitea (added
GITEA_DOMAIN/GITEA_ROOT_URL, dropped an unused duplicate-instance pair
of vars), grafana-stack (GRAFANA_ADMIN_PASSWORD), kestra (added
USERNAME/PASSWORD), kopia (SECRET_PASSWORD), nocodb (JWT_SECRET).
Also dropped an unused DOCKER var across most stacks where the
compose file hardcodes its path instead of referencing it.
