Fix redirect after account setup

@zac-broitman @lmcclung Updates to the account completion page as per discussion in PO BA Design meeting

Update Title, text, button labels and direct to the BC Registries Dashboard (instead of the Business Registry marketing page)


Start by locating the account completion page and the redirect used after account setup. Use the linked screenshot and the stated PO BA Design discussion to confirm the title, text, button labels, and destination; the work is done when the page matches those requirements and opens the BC Registries Dashboard.
