perf: optimize analytics app imports to avoid loading entire app store (calcom#23372)

* perf: optimize analytics app imports to avoid loading entire app store

- Add analytics service generation to app-store-cli build process
- Generate analytics.services.generated.ts with only analytics apps (dub)
- Update getAnalytics.ts to use AnalyticsServiceMap instead of full appStore
- Add NEXT_PUBLIC_IS_E2E to turbo.json globalEnv for generated files
- Reduces import footprint from 100+ apps to only analytics apps with AnalyticsService
- Follows same pattern as calendar services optimization from PR calcom#22450

* Reorder cli output

* fix: follow getCalendar pattern in getAnalytics and maintain alphabetical order in turbo.json

- Remove unnecessary object wrapping in getAnalytics.ts to match getCalendar.ts pattern
- Move NEXT_PUBLIC_IS_E2E to correct alphabetical position in turbo.json globalEnv
- Address PR feedback from keithwillcode

* chore: update yarn.lock after analytics optimization changes
