fix(analytics): import canonical github.com/zap-proto/zip (not hanzoai/zip)

Aligns clients/analytics with serve.go + every other in-tree clients/* subsystem,
which import github.com/zap-proto/zip. The original commit imported the OLD
github.com/hanzoai/zip, making analytics.Mount assert *hanzoai/zip.App while serve
passes *zap-proto/zip.App — a boot-time mount type mismatch. Removes the last in-tree
hanzoai/zip importer so once the migration lane re-releases the external subsystem
modules on zap-proto/zip, main boots with ONE zip.App type. (The DEPLOYED v1.786.17
is built off v1.786.13, which is all-hanzoai/zip, and is unaffected.)
