perf: convert app store imports to lazy getters for faster local dev

[Ashutosh0x]

What does this PR do?

This PR addresses issue #23104 by converting eager import() calls in generated app store files to lazy getter functions.

Problem

When any page loaded that imported the app store maps, all 110+ app modules would be compiled by Next.js even if only 1-2 were needed. This caused 10-12s initial page load times in local development.

Solution

Convert eager imports to lazy getter functions that only trigger the import when accessed.

Changes

• Modified build.ts to generate lazy getter functions for non-.tsx imports
• Updated all consumer utilities:
  • getCrm.ts
  • getCalendar.ts
  • getAnalytics.ts
  • getVideoAdapters.ts
  • apps/web/pages/api/integrations/[...args].ts

Expected Impact

80%+ reduction in local dev page load times (target: < 2s, down from 10-12s).

How should this be tested?

1. Run yarn app-store:build to regenerate the app store files
2. Start local dev with yarn dev
3. Measure initial page load times - should be significantly faster
4. Test app integrations (Calendar, CRM, Payment, Video) to ensure they still work correctly

Fixes #23104
