fix: hide already-filtered values from other spreadsheet column filters (#9386) (CP: 25.1)

[vaadin-bot]

This PR cherry-picks changes from the original PR #9386 to branch 25.1.

Original PR description

Description

In a SpreadsheetFilterTable with filters on multiple columns, opening any column's filter dropdown showed values from rows already hidden by other columns as unchecked, suggesting they were filtered by this column. Re-checking them did nothing because another column still hid the row.

Applying a second filter then implicitly added those already-hidden rows to the second column's filteredRows, so clearing the first filter did not bring the rows back — the second column now also filtered them.

Root cause: ItemFilter read spreadsheet.isRowHidden(r) for both building option lists and deciding which rows belong in its own filteredRows. That property reflects the union of all column filters, so each filter could not tell its own work from a sibling's.

Each ItemFilter now operates only on its own filteredRows. The dropdown option list omits values whose rows are all hidden by other columns via a new SpreadsheetFilterTable.getRowsHiddenByOtherFilters(self) helper. clearAllFilters does a second pass to refresh option lists so cleared siblings are reflected immediately.

Fixes #9329

Reproduction

@Route("spreadsheet-filter-cross-column")
public class SpreadsheetFilterCrossColumnPage extends VerticalLayout {

    public SpreadsheetFilterCrossColumnPage() {
        Spreadsheet spreadsheet = new Spreadsheet();
        spreadsheet.setTheme(SpreadsheetTheme.LUMO);
        spreadsheet.setHeight("400px");

        spreadsheet.createCell(0, 0, "Column A");
        spreadsheet.createCell(0, 1, "Column B");
        spreadsheet.createCell(0, 2, "Column C");

        spreadsheet.createCell(1, 0, "Alpha");
        spreadsheet.createCell(1, 1, "Foo");
        spreadsheet.createCell(1, 2, "Alice");

        spreadsheet.createCell(2, 0, "Beta");
        spreadsheet.createCell(2, 1, "Bar");
        spreadsheet.createCell(2, 2, "Bob");

        spreadsheet.createCell(3, 0, "Gamma");
        spreadsheet.createCell(3, 1, "Baz");
        spreadsheet.createCell(3, 2, "Carol");

        CellRangeAddress range = new CellRangeAddress(0, 3, 0, 2);
        SpreadsheetFilterTable table = new SpreadsheetFilterTable(spreadsheet,
                range);
        spreadsheet.registerTable(table);
        spreadsheet.refreshAllCellValues();

        add(spreadsheet);
    }
}

Column A	Column B	Column C
Alpha	Foo	Alice
Beta	Bar	Bob
Gamma	Baz	Carol

Steps to reproduce:

• Filter Beta in column A.
• Open the filter dropdown in column B → Bar shows up unchecked (before the fix), suggesting column B filtered it.
• Filter Foo in column B.
• Re-check Beta in column A → the row does not reappear (before the fix), because column B now also filters it.
