Homepage: give the user page its own login (dankuser)

The homepage user page + shared data now use a dedicated CADDY_HOMEPAGE_HASH
(username dankuser), separate from the shared family password (CADDY_BASICAUTH_HASH,
username dank, still used by the other vhosts) and the operator password
(CADDY_ADMIN_HASH, username frank, the /admin/ page). This lets the homepage be
re-logged independently without touching the other sites. deploy.sh renders the
new placeholder; the .env.example documents all three hashes.
