### What?
Updated `TypeWithID` so `deletedAt` can accept `null`.
### Why?
Generated collection types for trash use:
```
deletedAt?: string | null
```
`TypeWithID` previously only allowed `string | undefined`, so assigning
documents with `deletedAt: null` caused TypeScript errors.
Aligning the types fixes this mismatch and ensures `TypeWithID` is
compatible with the generated types.
### How?
Modified the `TypeWithID` definition to:
```
export type TypeWithID = {
deletedAt?: string | null
docId?: any
id: number | string
}
```
This makes `deletedAt` effectively `string | null | undefined`, matching
generated types and eliminating type errors.
