refactor(medications): mount the entry surfaces via ResponsiveSheet

Swaps the medication create/edit, intake create/edit, side-effect
log, and inventory add-pen mounts from the centred `<Dialog>` to
the shared `<ResponsiveSheet>` primitive so the same surfaces flip
to a bottom-anchored sheet on narrow viewports. The "log this
thing" mental model — measurement, mood, medication, intake,
side-effect, inventory — now lands on a consistent mobile shape.
Configuration surfaces (IntakeImport, ApiEndpoint, PhaseConfig)
stay centred per Decision G; the dialog primitive's new
`max-h-[calc(100dvh-2rem)]` default keeps them inside the viewport
on short / soft-keyboard screens without the previous per-callsite
`max-h-[90vh]` ceiling.
