"""Tests for the unified slicer-presets endpoint helpers.

The endpoint stitches together four preset sources (local / orca_cloud /
cloud / standard). It does NOT dedup across tiers — every tier surfaces
its full list so the user can pick any source. Bambu Cloud filament
metadata is enriched from same-named entries in the other tiers so it
can still score in the SliceModal's auto-pick. These tests pin the
enrich behaviour, the cloud-status mapping, and the per-user / sidecar
caches at the helper level — full HTTP integration is covered by the
routes test.
