Some bugs fixed in this PR
1. From UI any field could be chosen to group the query by it, while for
instance, RAW_JSON type (eg workflowRun.state) is not supported by
PostgreSQL to group a query by. Fix: removed it from the "group by"
fields options in FE + in BE -->
2. The BE check existed (isFlatFieldMetadataSupportedInGroupBy) but the
signature was malformed: it expected`{ fieldMetadataType,
fieldMetadataName, fieldMetadataIsSystem }` while every caller passes a
flat field metadata object with type/name/isSystem. So the check is
mis-wired — at runtime the destructured props are undefined, making it
always return true (validation bypassed). Fixed this.
3. Group by does not work with Morph relations if their direction is
ONE_TO_MANY. Added that constraint.
4. Group by with morph relations were broken even for MANY_TO_ONE,
because a morph is stored as one field per target
(polymorphicOwnerRocket, polymorphicOwnerSurveyResult…), each with its
own join column, but the frontend collapsed them into a single
polymorphicOwner field — so the backend tried to resolve a non-existent
polymorphicOwnerId. Fix: Frontend: added a target picker so you choose
the specific morph target (then its sub-field), storing the real
per-target field id. Backend: fixed validate-relation-subfield to use
the per-target field's own relationTargetObjectMetadataId instead of the
multi-target resolver that returned null.
5. (improvement) When an error occured in the query, the graph showed
"No data". Updated it to "error". (screenshot 1)
6. When a field used as a filter on a graph is deleted, it is not
deleted as a graph filter (which is ok because it would involve parsing
all the graph's configuration json to find whether a field is
referenced; there is no foreign key), which prevented from further
modifying the graph's filters. Fixed this + add an indicator that the
filter is can/should be removed (see screenshot 2)
7. "Ambiguous column name" PG error occurs when ordering by "creation
date" of a related field, because both objects have createdAt field.
Fixed it by adding table alias as prefix.
8. (improvement) While working on #5 I did not understand why we could
directly do `"objectMetadataNameSingular"."columnName" `while I expected
that for custom objects it would have to be
`_objectMetadataNameSingular`. that's simply because we use an alias
from the beginning. To add clarity, within groupBy code I replaced
`objectMetadataNameSingular` with `objectAlias` everywhere it is indeed
inherited from us using objectAlias.

# Introduction
In preparation of the workspace agnostic builder, we're migrating
`FlatEntityMaps` to be universal identifier oriented and based
As in the builder context there're won't be any ids at all
Please also note that the FlatEntity is a UniversalFlatEntity superset
From
```ts
import { type SyncableFlatEntity } from 'src/engine/metadata-modules/flat-entity/types/flat-entity-from.type';
export type FlatEntityMaps<T extends SyncableFlatEntity> = {
byId: Partial<Record<string, T>>;
idByUniversalIdentifier: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>;
};
```
To
```ts
export type FlatEntityMaps<
T extends SyncableFlatEntity | UniversalSyncableFlatEntity,
> = {
byUniversalIdentifier: Partial<Record<string, T>>;
universalIdentifierById: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>; // this might make more sense to be migrated to universalIdentifiersByApplicationUniversalIdentifier but it's the main topic of this PR
};
```
## Low level maps tools
Had to refactor find | create | delete | replace | find-many | get-sub
tools ( through mutations and or throw equivalent )
- Create resolvers for each type of charts which needs data
transformation after the group by operation: Bar Chart, Line Chart and
Pie Chart
- Move all the utils to the backend and refactored some into services
This allows all the computation to be done in the backend, improving
performances in the frontend.
