Add CSP (Content Security Policy) support for Livewire v4

[musilondrej]

Livewire v4 introduced a csp_safe mode with a dedicated Alpine CSP build (livewire.csp.esm). When using this mode, PowerGrid throws a console error:

Uncaught Error: CSP Parser Error: Unexpected token: PUNCTUATION ")"

Alpine's CSP parser cannot handle the this.$js() callback syntax. The table renders fine, but the @script logic (pgRowTemplates, pgResourceIcons, pgActions, pgActionsHeader) never executes.

It would be great if PowerGrid supported Livewire v4's CSP mode as documented at https://livewire.laravel.com/docs/4.x/csp.

Environment

• PowerGrid: v6.9.2
• Livewire: v4
• Laravel: 12
