Fix applications query cartesian product causing read timeouts (#19892)
## Summary

Same fix pattern as #19511 (`rolesPermissions` cartesian product).

The `Settings > Applications` page was hitting query read timeouts in
production. The offending SQL came from
`ApplicationService.findManyApplications` / `findOneApplication`, which
loaded **5 `OneToMany` children** in a single query via TypeORM
`relations`:

```
logicFunctions × agents × frontComponents × objects × applicationVariables
```

Postgres returns the Cartesian product of all five — e.g. 20 logic
functions × 5 agents × 30 front components × 100 objects × 10 variables
= **3M rows for ~165 distinct records**, which trivially exceeds the
read timeout.

## Changes

- **`findManyApplications`** — dropped all `OneToMany` relations. The
frontend `FIND_MANY_APPLICATIONS` query only selects scalar fields and
the `applicationRegistration` ManyToOne, so joining the children was
pure waste at the list level.
- **`findOneApplication`** — kept the cheap `ManyToOne` / `OneToOne`
joins (`packageJsonFile`, `yarnLockFile`, `applicationRegistration`) on
the main query and fetched the 5 `OneToMany` children in parallel via
`Promise.all`, reattaching them on the entity. Same shape as
`WorkspaceRolesPermissionsCacheService.computeForCache` after #19511.
- **`application.module.ts`** — registered the 5 child entity
repositories via `TypeOrmModule.forFeature`.

The other internal caller (`front-component.service.ts →
findOneApplicationOrThrow`) only reads
`application.universalIdentifier`, so the extra parallel single-key
lookups remain far cheaper than the previous 8-way join with row
explosion.

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.
