The legacy SMARTMUSIC_ prefix dates from when the project was specced
as "smart-music" before being renamed to Minstrel. Hard cutover to
MINSTREL_* across config.go, tests, config.example.yaml, README, and
docker-compose. Also renames SMARTMUSIC_CONFIG in cmd/minstrel/main.go
which was missed in the original audit.
Also seeds Auth.AdminBootstrap.Username = "admin" in Default() so
MINSTREL_DATABASE_URL is the only env var required for a fresh prod
deployment — the bootstrap auto-generates a password and prints it
to stderr. Drops the now-redundant MINSTREL_AUTH_ADMIN_USERNAME=admin
line from the README quickstart and docker-compose.
M1 follow-up from the #363 final review: guards
MINSTREL_BRANDING_APP_NAME and _DESCRIPTION against empty-string
overrides — empty would have shipped <title></title> to share-preview
crawlers.
