Two changes that drop the friction in self-hosting RefBoard so the install
story becomes "docker compose up, open the URL".
1. JWT_SECRET is now optional. On first boot the backend generates a
64-byte random secret and persists it in the existing settings table.
process.env.JWT_SECRET still wins when set, so ops setups that manage
secrets out-of-band are unaffected. The prod-throws-without-env guard
is gone (auto-generation is a strictly safer default than the previous
hardcoded dev fallback).
2. STORAGE_BACKEND=fs|minio picks between MinIO (default, unchanged) and
a new local-filesystem adapter. The FS adapter exposes a fake minioClient
that mirrors the methods RefBoard calls (statObject, getObject,
getPartialObject, listObjectsV2, putObject, removeObject(s), bucketExists,
makeBucket), so consumers swap require('./minio') for require('./storage')
and nothing else changes. Sidecar .mime files hold Content-Type so the
range-aware media proxy still serves the right response headers.
examples/compose/minimal-fs.yml is the single-container variant that uses
the FS adapter. The default docker-compose.yml still spins up MinIO.
README quick-start collapses to one block (cp .env, docker compose pull,
docker compose up -d). The first user you register on the Login screen is
auto-promoted to admin, same as before.
