feat: show result count on colorbox swatch filter options in Hyva theme

[ahuininga-orisha]

Summary

In Tweakwise, a filter attribute can be configured to show the number of matching products next to each option (the "Show amount of results" setting). For Colorbox-type filters this worked in the Luma theme but was silently missing in the Hyvä theme — shoppers saw the colored swatches with no counts at all.

This fix brings the Hyvä colorbox filter in line with Luma: when "Show amount of results" is enabled in the filter template, each swatch option now shows a (N) count below the color box.

Changes

File	What changed
src/view/frontend/templates/product/layered/swatch.phtml	Render result count below each swatch when shouldDisplayProductCountOnLayer() is true
src/view/frontend/templates/product/layered/swatch.phtml	Changed flex direction to flex-col items-center so the count stacks below the swatch box

How to test

Scenario 1 — Count is shown when "Show amount of results" is enabled

1. In the Tweakwise Navigator app, open the filter template for your category. Set a color attribute to display type Colorbox and enable Show amount of results.
2. Run bin/magento cache:clean.
3. Open the category page in a Hyvä-themed store.
4. Verify: each color swatch shows a (N) count below the color box.

Scenario 2 — Count is hidden when "Show amount of results" is disabled

1. Disable Show amount of results on the same attribute.
2. Run bin/magento cache:clean.
3. Open the same category page.
4. Verify: no count appears on any swatch option.

Scenario 3 — Luma theme is unaffected

1. Switch to a Luma/blank-theme store view with the same filter template (counts enabled).
2. Open the category page.
3. Verify: counts still render correctly — no regression.
