Integrate current origin/dev (vendor-core completion plus frontend
maintainability) into the work-order board shell branch.
Resolved semantic conflicts against the new frontend-maintainability
ESLint conventions introduced on dev: guard non-boolean && left
operands with Boolean()/!=null and replace raw <p> with the shared
Text component (media-upload-modal). PR #39 board shell/detail modules
and hooks preserved; merged vendor-core behavior and Text/ESLint
conventions preserved.
