feat: add Country of Origin field to product Reverb tab

Adds origin_country_code (ISO 3166-1 alpha-2) to the per-product
Reverb tab with a Select2 searchable country dropdown.

- DB: origin_country_code VARCHAR(2) added to oc_reverb_product_map
  in both install() CREATE TABLE and migrate() addColumnIfMissing()
  so existing installs get the column automatically on next load
- saveProductMap(): persists the value; sanitised to 2-char uppercase
- saveProductReverb() event handler: reads reverb_origin_country_code
  from POST and passes it through to saveProductMap()
- ProductMapper::toReverb(): includes origin_country_code in the
  listing payload when set
- productTab(): loads oc_country list via model_localisation_country,
  resolves the store default from config_country_id, falls back to
  that default when the saved value is empty
- Template: Select2 country dropdown placed above the Handmade field;
  initialised alongside the existing category Select2
