hive resume crashes: getAllAgents() removed

## Bug

`hive resume` crashes immediately with:

```
Error: getAllAgents() removed — use CodeshipClient API instead
    at file:///app/dist/types/db-types.js:47:11
    at file:///app/dist/cli/commands/resume.js:38:37
```

## Root Cause

Same DB-to-API migration issue as #655. The resume command still calls the old `getAllAgents()` DB function.
