Put job dashboard on WC My Account dashboard?

Lots of people use WPJM and WooCommerce together. WooCommerce already outputs a user dashboard of sorts using `[woocommerce_my_account]`. We should have at least some integration that would allow the job dashboard to show up on that page, as opposed to being on its own page.

Start by tracing the [woocommerce_my_account] entry point and WP Job Manager's existing job-dashboard entry point, then compare how each renders account content. Define the integration boundary and verify that the job dashboard appears within the WooCommerce My Account page without requiring its own page.
