feat(leads): campaign-grouped leads with table, infinite scroll, and CRUD actions

[Rishavraaj]

Summary

• Group leads by campaign on the leads list page with campaign name + lead count
• Campaign leads table with columns: Name, Company, Title, Email, Status, Source, ICP Profile, Actions
• Infinite scroll on campaign leads table (50/page)
• Add Lead sheet on both leads list page and campaign leads page
• Revert action for converted leads (also deletes the associated deal on backend)
• Action buttons use icon tooltips (convert → deal, revert, view deal, delete)
• ICP Profile cell links to /icps/[id]; Name cell links to /leads/[id]
• Hover underline on name columns across leads, campaigns, and ICP list pages
• Sidebar nav order: Deals → ICPs → Campaigns → Leads
• Removed unused LeadsList component and getTableViewLeadsInfinite query

Changes

Backend

• leads.service.ts: Revert now deletes the associated deal before unlinking

Frontend

• LeadLists.tsx: Campaign-grouped leads page with Add Lead sheet
• LeadsInList.tsx: Full column set, infinite scroll, tooltips, create/revert wired
• LeadDetail.tsx: Revert button for converted leads
• application-layout.tsx: Sidebar nav reordered
• query-options.ts: Added getLeadsInfinite, removed unused exports
• CampaignsList.tsx, IcpList.tsx: Hover underline on name column

Test plan

• Leads page shows campaigns grouped with lead count
• Clicking campaign row navigates to /leads/campaign/[id]
• Campaign leads table shows all columns correctly
• Infinite scroll loads more leads on scroll
• Add Lead sheet opens and creates lead successfully
• Convert to deal works; Revert removes deal and resets status
• ICP Profile cell links to correct ICP detail page
• Name cell links to lead detail page
• Hover underline visible on name in leads, campaigns, ICP lists
