Minor fixes and a smarter import flow.
What's new
XLSX template downloads. The import wizard now generates Excel templates directly — no more CSV wrangling. Headers are prefixed with attr_ to avoid collisions, and columns sort themselves sensibly.
Improvements & fixes
Fixed crashes when XLSX generation failed or returned incomplete files.
Import templates now include data validation. Less room for creative interpretations of what belongs in each field.
Unit preferences now respect entity-level settings. The hierarchy actually works the way you'd expect.
File upload service reliability stability improvements; making the service less error prone and resiliant to crashes for long lived sockets.
