🎨 Improved y-axis scaling and country names in Analytics

[peterzimon]

Newsletter chart y-axis scaling

The Avg. click rate chart on Analytics → Newsletters used a fixed-step rounding (nearest 0.1) for its y-axis, which snapped the upper bound to 10% even when the click rate was a fraction of a percent — making sub-1% bars effectively invisible.

This change brackets the y-axis to the actual data:

• < 1% → 0% – 1%
• 1% – 10% → 0% to the next whole percent above the max
• 10% – 100% → 0% to the next multiple of 10 above the max

The avg reference line value is included in the bracket pick, so the dashed avg line is always inside the visible range (previously it could fall outside and be hidden).

Examples:

Max value	Old upper	New upper
0.4%	10%	1%
3.2%	10%	4%
9.2%	10%	10%
28%	30%	30%
36%	40%	40%

Country names in Web analytics

The Locations card used to render the official ISO country names from i18n-iso-countries ("Russian Federation", "Taiwan, Province of China", "Korea, Republic of"…), which read awkwardly. We now ask the library for the short/common form via getName(code, 'en', {select: 'alias'}) and add a few manual overrides for countries where the library has no alias. Net result:

• Russian Federation → Russia
• People's Republic of China → China
• Taiwan, Province of China → Taiwan
• Islamic Republic of Iran → Iran
• Korea, Republic of → South Korea
• United States of America → United States
• United Kingdom → UK
• Viet Nam → Vietnam
• Czech Republic → Czechia
• Lao People's Democratic Republic → Laos
• Moldova, Republic of → Moldova
• Syrian Arab Republic → Syria
• …plus a handful of similar tidy-ups

Test plan

• Open Analytics → Newsletters on a site with a sub-1% avg click rate; verify the y-axis runs 0%–1% and bars are visible
• Confirm the Avg. open rate chart still looks right at typical 20–40% values (0%–30%, 0%–40%)
• Hover bars and confirm the tooltip still shows the right numbers
• Confirm the dashed avg line is visible and lands at the correct height
• Open Analytics → Web traffic and check the Locations card / country filter — names should be the short form (Russia, China, Taiwan, South Korea, etc.)

Walkthrough

Two parallel display fixes across the stats and posts apps, plus a newsletter chart refinement. The STATS_LABEL_MAPPINGS country override section in both apps removes US, TWN, TW, and CN entries and adds GB, KR, LA, MD, and SY. All getCountryName helper functions (in stats locations-card.tsx, stats-filter.tsx, posts Web locations.tsx, and posts PostAnalytics stats-filter.tsx) now pass {select: 'alias'} to countries.getName, changing which display name is returned for a given country code. Separately, the newsletter bar chart y-axis calculation is updated to include the active tab's average reference line value (avgOpenRate or avgClickRate) when computing the maximum bound, then applies threshold-based bucketing to derive finalMax, replacing the previous min/max rounding approach.
