auth: HTTP helper + token storage (C3, C4)

Add libpanto http_helper (non-streaming request/response over the global
client, plus dotted-JSON-path readers) and token persistence in auth.zig
(load/save/delete TokenSet under an embedder-chosen auth dir, owner-only
files). Add $PANTO_HOME/auth to the panto_home layout.
