Add link feature filters to links UI and API

[marcusljf]

Introduces link filtering by enabled features (e.g., conversion tracking, geo targeting, UTM tags) in both the API and the UI. Adds a utility to build Prisma where clauses for these features, updates Zod schemas to accept the new filter, and enhances the UI to allow users to filter links by feature with counts and icons.

Behaves similarly to the link tag filter.
