base_url is the URL you are about to call, with any query string and
fragment removed. Returns "Bearer <token>" when a token can be obtained
for it — minting one if no usable entry covers it yet — and
"Basic <credentials>" otherwise.
Asking for the token rather than first checking whether one exists is what
makes the Bearer path reachable at all. Nothing else mints the first token, so
gating on AccessTokens.exists?/1 left every call authenticating with the
long-lived client credentials for the life of the node.
Callers with no target base URL — the log writers, and every call this SDK
itself makes to intake — get Basic, and so does GenerateAccessToken, which
uses basic_header/0 directly and must not present a Bearer to the endpoint
that issues them.
