🎨 Cleaned up country names in Post analytics

ref https://linear.app/tryghost/issue/NY-1365/

- mirrored the cleanup from the Web analytics PR (#28708) in the Post analytics web tab: the Locations card and the country filter showed the official ISO names from i18n-iso-countries ("Russian Federation", "Taiwan, Province of China", …)
- switched the library lookup to {select: 'alias'} so the short/common form is returned when one exists
- added the same explicit overrides for entries where i18n-iso-countries has no alias or picks the wrong form: GB → United Kingdom, KR → South Korea, LA → Laos, MD → Moldova, SY → Syria
- dropped the now-redundant US/TW/TWN/CN entries from the posts app's STATS_LABEL_MAPPINGS
