Repo-wide sweep for the same flat 1px-border "fake card" pattern
already fixed in Dashboard/Kanban/JobDetailsDialog/auth pages this
session -- AddJobModal, Attachments, CompaniesTable, Correspondence,
EditJobDialog, and the admin audit/system/users pages all had a table
container or content box using border+divider instead of the
floating-shadow treatment used everywhere else now.
Left AppShell.tsx/App.tsx alone -- their border:1px+divider instances
are icon-button and badge outlines, not card containers; that's a
different, correct use of the pattern.
