Added column drag and drop reordering with persistant sizing and ordering

[jschick04]

Resolves #332

[Copilot]

Pull request overview

Adds persisted column sizing and drag-and-drop column reordering to the EventTable UI, introducing defaults and preference storage so column layouts survive app restarts.

Changes:

• Reworked event_table.js to use an init/dispose lifecycle, add column drag-reorder, and persist column resize events back to .NET.
• Added persisted ColumnWidths + ColumnOrder to EventTableState, along with new actions/reducers/effects and a “Reset Column Defaults” menu item.
• Introduced centralized ColumnDefaults (enabled columns, order, widths) and removed hardcoded column-width CSS.

src/EventLogExpert/Shared/Components/TableColumnMenu.razor.cs:54

• ToggleColumn dispatches both EventTableAction.ToggleColumn and EventTableAction.LoadColumns(). With the new EventTableEffects.HandleToggleColumn already computing widths/order and dispatching LoadColumnsCompleted, the extra LoadColumns causes a second redundant state update/render (and potentially extra JS re-init work). Consider removing the LoadColumns() dispatch here (or changing the effect to only update preferences and rely on a single load action) so toggling a column results in one state transition.

    private void ToggleColumn(ColumnName columnName)
    {
        Dispatcher.Dispatch(new EventTableAction.ToggleColumn(columnName));
        Dispatcher.Dispatch(new EventTableAction.LoadColumns());
    }
