Schema Templates grid has no items-per-page control (uses the p-table pager, not the shared paginator)

[vshvets-bc]

Symptom

The Schema Templates list paginates with PrimeNG's default p-table pager — just the page arrows. There is no rows-per-page selector, so the page size cannot be changed. Every other grid in the app shows the shared paginator with a 10 / 25 / 50 / 100 / 500 selector, so this grid is both inconsistent and less usable.

Where

frontend/src/app/views/schema-templates/schema-templates.component.html:88-89 enables the table's own paginator:

<p-table
    [value]="templates"
    [paginator]="true"
    [rows]="pageSize"
    ...

The convention elsewhere is the shared <app-paginator> (frontend/src/app/modules/common/paginator/), as used by the Schemas grid.

Note

SchemaTemplatesComponent.onPage currently reads PrimeNG's {first, rows} payload:

public onPage(event: any): void {
    this.pageIndex = Math.floor((event.first || 0) / (event.rows || this.pageSize));
    this.pageSize = event.rows || this.pageSize;
    this.loadTemplates();
}

app-paginator emits {pageIndex, pageSize} instead, so the handler has to change with the template. The default pageSize = 20 is also not one of the paginator's options, so it would be appended to the selector's list.
