auth: drop ENTIRE_AUTH_BASE_URL from user-facing login hints
main·
Commit

The "where do I log in" hints now just say entire login (plus
entire auth use to switch between existing logins) instead of
ENTIRE_AUTH_BASE_URL=<url> entire login. The env-var override stays a
power-user mechanism; fully sunsetting it (+ entire login --server) is
tracked in COR-393.
