fix: resolve GitHub Actions CI failures (lint, typecheck, test, format)

- Remove unused `Locale` type imports from admin pages
- Fix type annotations in easy-pay client test (CID fields as string | undefined)
- Replace `as any` with proper types in limits test
- Fix listSubscriptions test mock response structure (data.data.items)
- Fix formatting with Prettier
