Update to latest aggrid / nicegui API

[xaptronic]

Summary: Pre-Built Bundle Branch (Main)

Core Changes

Two Python Classes (aggrid.py)

• AgGridEnterprise — AG Grid Enterprise with AG Charts Community (smaller bundle)
• AgGridEnterpriseCharts — AG Grid Enterprise with AG Charts Enterprise (full features)

Two JavaScript Bundles

• dist/index.js — imports AgChartsCommunityModule
• dist-enterprise-charts/index.js — imports AgChartsEnterpriseModule

Key Updates from Original

• AG Grid 35.0.0 (was older version)
• NiceGUI 3.0.0+ compatibility (ESM module loading)
• New theming API — AgGrid.themes[theme].withPart(colorSchemeVariable)
• Dark mode support — MutationObserver watches body--dark class
• New AG Grid options syntax — rowSelection: {mode: "multiRow"}, cellSelection: true
• Charts module registration — IntegratedChartsModule.with(AgChartsCommunityModule)
• Renamed class from AgGrid → AgGridEnterprise (avoids conflict with NiceGUI's built-in)

AgGridEnterprise.license_key = "YOUR_KEY"
