Risk HIGH: Adds incoming webhook documentation with new source pages, refactors the sources overview, and introduces a new isLegacy UI prop to shared sidebar navigation components.

Reasons

• Modifies shared UI components (components/ui/CollapsibleNavItem.tsx and components/ui/Page/Sidebar.tsx) to add an isLegacy prop and "Legacy" tag rendering — triggers HIGH per component modification rule
• Modifies shared type definitions in data/types.ts (SidebarPage, SidebarSection, SidebarContent) which affect the entire sidebar system
• Adds 6 new MDX pages (clerk.mdx, custom.mdx, posthog.mdx, stripe.mdx, supabase.mdx, workos.mdx) — triggers MEDIUM
• Modifies sidebar navigation config (data/sidebars/integrationsSidebar.ts) — triggers MEDIUM
• Substantially rewrites content/integrations/sources/overview.mdx (75 additions, 189 deletions) — triggers MEDIUM

Notes

• The component changes are additive (new optional isLegacy prop with default false), so they should be backward-compatible, but a reviewer should verify no regressions in sidebar rendering across all pages
• Verify the new "Legacy" Tag with color="yellow" renders correctly and consistently in all sidebar contexts (collapsible items, sub-pages, and standalone items)
• Check that the 6 new source pages have correct frontmatter, valid internal links, and appear properly in the sidebar navigation
• Review the overview.mdx rewrite to ensure no important content was lost during the refactor
• The PR description says "WIP" — confirm whether this is ready for merge or if additional content is expected
