fix: dead sidebar/wallet/leads/marketplace navigation links

- DashboardLayout sidebar: Leads/Credits/Settings/Logout pointed to
  routes with no matching file (404). Leads now routes to the real
  accepted-leads page; Credits/Settings/Logout reuse the working
  /dashboard?nav= deep-link into the main dashboard's tab switcher
  (fixes Logout leaving users authenticated on a 404).
- wallet/buy.tsx, wallet/payu-return.tsx: post-purchase, cancel, and
  payment-verification redirects targeted non-existent /dashboard/wallet;
  now redirect to the existing credits/wallet tab.
- leads/accepted.tsx already contained a detail view gated on
  useParams().id, but was only registered as a flat route with no :id
  segment, so the detail view was dead code. Split into
  leads/accepted/index.tsx + leads/accepted/[id].tsx backed by a shared
  AcceptedLeadsView component.
- Added marketplace/[id].tsx: "View Requirement" buttons navigated to
  a route that never existed.
