## Summary
Follow-up to the upgrade CTA placement experiment (#45858). The
`PlanUsageCard` count metrics (Monthly active users) were abbreviated to
`50k`, which reads ambiguously. This shows them in full with thousands
separators (`50,000`) to match the pricing page.
- `Monthly active users` row now renders e.g. `8,200 / 50,000` instead
of `8.2k / 50k`.
- Collapses the two count formatters (`formatCount` /
`formatCountLimit`) into one `toLocaleString()` call so the current
value and limit always use the same format.
- GB metrics (Egress, Database size, File storage) are unchanged.
## Test plan
- [ ] On the org projects page with the `org_projects_list` variant, the
Monthly active users row shows full numbers (`0 / 50,000`).

thousands separators instead of abbreviated notation, improving clarity
