## Summary
- Fix `useSubscriptionCredits` test to use cents (500) instead of
incorrect micros (5000000)
- Despite API field names containing `micros`, the server actually
returns cents (1/100)
- Add clarifying comment to `usdToMicros()` about the cents vs micros
confusion
- Increase performance test threshold from 10ms to 50ms to reduce
flakiness
## Context
The API response fields are named `amount_micros`,
`cloud_credit_balance_micros`, etc., but the server actually sends
**cents** (1/100 of a dollar), not true micros (1/1,000,000).
Verified with real API response:
```json
{
"amount_micros": 2725.927956, // = $27.26 when divided by 100
"currency": "usd"
}
```
## Changes
-
`tests-ui/tests/platform/cloud/subscription/composables/useSubscriptionCredits.test.ts`:
Update test values from micros to cents
- `packages/shared-frontend-utils/src/formatUtil.ts`: Add clarifying
documentation
- `tests-ui/tests/store/modelToNodeStore.test.ts`: Increase performance
test threshold to reduce flakiness
## Test Plan
- ✅ All unit tests pass (3202 passed, 206 skipped)
- ✅ Linting passes
- ✅ Formatting passes
