fix(medications): keep dose-window defaults off the client server graph

The dose-window editor pulled DOSE_WINDOW_DEFAULTS from
@/lib/analytics/compliance, dragging the server-only scheduling graph
(which imports node:async_hooks) into the client bundle. Turbopack
rejected the client chunk; tsc does not model the boundary so the type
check stayed green.

Move the constant into a leaf module with no server imports and
re-export it from compliance so the server path is unchanged. The
client-reachable editor now imports the leaf directly.
