Stashes a per-request Connect stripe_account id into the process
dictionary for the lifetime of the request.
The scope value is resolved from a compile-time MFA tuple — never
from a raw HTTP header or query parameter. The configured
tenancy function receives the %Plug.Conn{} as its last argument so
the host app can read conn.assigns, session data, or subdomain to
decide which connected account the request operates on.
Usage
plug Accrue.Plug.PutConnectedAccount,
from: {MyAppWeb.Tenancy, :current_stripe_account, []}MyAppWeb.Tenancy.current_stripe_account/1 (note: Accrue appends
conn as the trailing argument, so the declared arity is
length(args) + 1) must return one of:
nil— platform scope (default; plug is a no-op)- a binary
"acct_..."id - an
%Accrue.Connect.Account{}struct
Any other return shape raises ArgumentError.
