- Remove New/My Leads/All Leads tabs — redundant now that contacts
are on a separate page; all leads shown as a flat list
- Remove row checkboxes (selectionMode="none") — bulk actions weren't
wired to any backend and confused QA
- Move Search + Columns + Export into the header row alongside the
title — cleaner single-row layout
- Remove BulkActionBar + AssignModal + WhatsAppSendModal + MarkSpamModal
imports and JSX — dead code without checkboxes
- LeadTable: new selectionMode prop (default "multiple" for back-compat)
- Same cleanup on Contacts page (no checkboxes)
