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.

Forgot to include this in the previous commit (6d1709c). The new
config field's example block needs to be in the canonical yaml so
operators copying it in get the doc.
