TableStylingWorkflow improvements

Add style title, hide style, long/lat column in advanced mode

"Style" dropdown now shows TableStyles instead of TableColumns

Add symbology dropdown to advanced mode (was only showing in basic mode)

Show "Variable" in "Fill color" if color column name doesn't match style name (eg style isn't generated by TableAutomaticStylesStratum)

Other Changes

• Protomaps Polygon features now only use PolygonSymbolizer (instead of PolygonSymbolizer and LineSymbolizer)
