v0.1.27

Fix: Throughput API v1 available - Details posted to Irving. POWERBI_KEY was missing from the .ENV file, so was not live.
Add: Editor now supports editing a mix's resolved formula directly, with % and kg dual entry on ingredient rows
Fix: Mix Editor should bring through correct ingredients. New resolved formula (same logic we use in Mix Calculator).
Fix: Security headers on all API responses (hardening)
Add: New mix button available on the Mix Editor.
Add: New ingredient button available on the Ingredient Editor
