v0.3.6

IGNIS branding update

Branding-only patch. Adds the approved Unicorn Station logo and native Home Assistant 2026.3+ brand images, source PNG and proportional export sizes. Updates product display names while preserving technical integration/domain/entity/API/database/registry identities.

No functional policy, engine or automation changes. Installation and Live verification remain separate user actions. Older HA/HACS CDN pictures may require a separate brands publication; prepared PNGs and details are in brand/README.md.
