The subscription dashboard links for Learn More and Website now direct users to the subscription page instead of the accounting page. This helps users reach the relevant information faster and avoids confusion when exploring subscription features.

before this commit, on clicking learn more or website it redirect to accounting page.

after this commit, it will redirect subscription page.

This update removes a redundant database index in the event barcode area because an existing unique rule already provides the same coverage. It helps keep the system leaner and avoids unnecessary database maintenance without changing user-facing behavior.
