Pull request overview

This PR removes the legacy SystemJS-based demos infrastructure and shifts demos toward an esbuild-bundled model (including CSP/visual-test pipeline updates). It also includes related cleanup/fixes in the PivotGrid wrapper generation (to avoid nested-option naming/selector conflicts) and a DataController paging sync adjustment with new Jest coverage.

Changes:

• Removed SystemJS-related demo tooling/configuration and dependencies; updated demo templates and CI workflows to use esbuild bundles (including sharded build artifacts for visual tests/CSP checks).
• Refactored demo dev server + bundling utilities to support on-demand (lazy) in-place demo bundling.
• Improved grid DataController/DataHelperMixin typing and introduced a new integration test for paging.pageIndex synchronization.

🔵 Needs a closer look

The change set is very broad (mass demo edits + build pipeline removals), so it should be validated by a human via running the demos/tests affected by the new non-SystemJS bundling flow.

🟡 Changes recommended

There is still at least one Angular demo that contains SystemJS-era packageConfigPaths/modulePrefix logic, so the “remove SystemJS” cleanup appears incomplete.
