A4A: Remove dead code with hardcoded boolean variables

[jkguidaven]

Context: pfSQfS-1sJ-p2

Proposed Changes

This pull request primarily removes temporary feature flags and placeholder logic related to program links, license issuing, and "Learn more" links throughout the partner directory and billing UI. The changes simplify the codebase by eliminating unused variables and conditionals, ensuring that program links and license issuing buttons are always shown, and removing placeholder "Learn more" links that were not yet implemented.

Key changes include:

Removal of temporary feature flags and placeholder logic:

• Removed the displayProgramLinks flag and now always display programLinks in the partner directory dashboard (index.tsx). [1] [2] [3]
• Removed the partnerCanIssueLicense flag and related conditionals; the "Issue new license" button is now always enabled and links directly to the marketplace in billing and licenses UI components (billing-dashboard.tsx, license-list/empty.tsx, licenses-overview/index.tsx). [1] [2] [3] [4] [5] [6]

Cleanup of placeholder "Learn more" links:

• Removed unused and placeholder "Learn more" links and associated flags from the license list empty state and revoke license dialog components (empty.tsx, revoke-license-dialog/index.tsx). [1] [2]

Minor code cleanup:

• Removed unused imports (e.g., Gridicon) from the license list empty state component (empty.tsx).

Why are these changes being made?

Ensures our codebase are maintainable by removing irrelevant codes.
