Enable Feature Flag on My Business Registry dashboard for numbered incorporation

@mstanton1 to confirm what is needed prior to refinement.

Can a dev check if there is a feature flag which prevents a user from seeing the Incorporate Now button?

Start by locating the My Business Registry dashboard component and the rendering logic for the Incorporate Now button, then trace any feature-flag configuration it uses. Done means confirming whether a flag controls the button and documenting the required flag or follow-up change; no file or test is named in the issue.
