Restore to new project showed $0 Additional Monthly Compute for nano
projects on paid plans, because the cost estimate hardcoded nano and
pico to $0 regardless of plan. It now prices them at the micro rate on
paid plans, matching how they're billed (and how Disk Management already
displays them).
Fixes FE-4427

## Summary by CodeRabbit
- **Bug Fixes**
- Corrected monthly pricing estimates when restoring a project with pico
or nano compute sizes on paid plans.
- Free plans continue to show no compute charge.
- Pricing for micro and small compute sizes remains calculated using
their expected rates.
- **Tests**
- Added coverage for compute pricing across free and paid plans and
multiple instance sizes.
