Router helpers for mounting Accrue webhook endpoints.

Usage (Phoenix router)

import Accrue.Router

pipeline :accrue_webhook_raw_body do
  plug Plug.Parsers,
    parsers: [:json],
    pass: ["*/*"],
    json_decoder: Jason,
    body_reader: {Accrue.Webhook.CachingBodyReader, :read_body, []},
    length: 1_000_000
end

scope "/webhooks" do
  pipe_through :accrue_webhook_raw_body
  accrue_webhook "/stripe", :stripe
end

Multi-endpoint (Phase 4 Connect ready, D2-18)

The macro accepts a processor atom. Calling accrue_webhook/2 multiple times with different processors works natively:

scope "/webhooks" do
  pipe_through :accrue_webhook_raw_body
  accrue_webhook "/stripe", :stripe
  accrue_webhook "/connect", :stripe_connect
end

Each resolves to its own signing secret via Accrue.Config.
