oniani1 d583984bf0 fix(api-key): batch role resolution with DataLoader to fix N+1 (#19590)
## Summary

The `role` @ResolveField on `ApiKeyResolver` calls `getRolesByApiKeys`
with a single-element array per API key. When a query returns N API
keys, this produces N separate DB queries to resolve their roles.

This adds an `apiKeyRoleLoader` to the existing DataLoader
infrastructure. All API key IDs in a single GraphQL request are
collected and resolved in one batched query.

- Before: N queries (one per API key)
- After: 1 query (batched via DataLoader)

## Changes

- `dataloader.service.ts` - new `createApiKeyRoleLoader` method,
delegates to `ApiKeyRoleService.getRolesByApiKeys`
- `dataloader.interface.ts` - `apiKeyRoleLoader` added to `IDataloaders`
- `dataloader.module.ts` - import `ApiKeyModule` so `ApiKeyRoleService`
is available
- `api-key.resolver.ts` - `role()` now uses
`context.loaders.apiKeyRoleLoader.load()` instead of calling the service
directly

## Test plan

- [ ] Verify `apiKeys { id role { label } }` query returns the same
results as before
- [ ] Confirm only 1 role_target query fires regardless of how many API
keys are returned

Why Twenty

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
