refactor: remove migrated artist creation code from Recoup-Chat (MYC-3928)

[sweetmantech]

Summary

• Delete app/api/artist/create/route.ts (REST endpoint migrated to recoup-api POST /api/artist)
• Delete lib/tools/createArtist.tsx (MCP tool now provided by recoup-api MCP server)
• Delete lib/supabase/copyRoom.ts (only used by deleted createArtist.tsx)
• Update lib/tools/getMcpTools.ts to remove create_new_artist registration
• Create types/CreateArtistResult.ts shared type for UI components
• Update UI component imports to use new type location

Test plan

• All 9 unit tests pass in Recoup-Chat (pnpm test)
• Build succeeds (pnpm build)
• Verify create_new_artist MCP tool works via recoup-api in staging
• Verify CreateArtistToolResult UI component renders correctly

Notes

• lib/supabase/createArtistInDb.ts retained - still used by /api/workspace/create endpoint
• This completes MYC-3928 cleanup after MYC-3923 (MCP migration) and MYC-3927 (endpoint refactor)
