## Context
Text fields were being sorted case-sensitively on the backend (e.g.,
'Apple', 'apple', 'Banana' would sort as 'Apple', 'Banana', 'apple').
This resulted in unexpected sorting behavior that differed between the
frontend Apollo cache sorting and backend database sorting.
## Changes
### Backend (packages/twenty-server)
- **`graphql-query-order.parser.ts`**:
- Added `shouldUseCaseInsensitiveOrder()` helper that returns `true` for
TEXT, SELECT, and MULTI_SELECT fields
- Added `buildOrderByColumnExpression()` method that wraps column
expressions with `LOWER()` for case-insensitive sorting
- Updated `parse()` and `parseObjectRecordOrderByForScalarField()` to
use the new helpers
- Updated `parseObjectRecordOrderByForRelationField()` to apply LOWER()
to nested text fields
- **`parse-composite-field-for-order.util.ts`**:
- Added `shouldUseCaseInsensitiveOrder()` helper for composite subfields
- Updated composite field parsing to apply `LOWER()` to subfields of
type TEXT (e.g., `name.firstName`, `name.lastName`)
### Frontend (packages/twenty-front)
- **`sort.ts`**:
- Updated `sortAsc()` to use case-insensitive comparison
(`toLowerCase()`) for string values
- `sortDesc()` automatically benefits from this since it delegates to
`sortAsc()`
- Ensures Apollo cache sorting matches backend behavior
## Example
Before:
```sql
ORDER BY "person"."name" ASC
```
Result: ['Apple', 'Banana', 'apple', 'cherry']
After:
```sql
ORDER BY LOWER("person"."name") ASC
```
Result: ['apple', 'Apple', 'Banana', 'cherry']
## Testing
- Manual testing of sorting on People and Companies views
- Verified frontend cache sorting matches backend results
Fixes https://github.com/twentyhq/twenty/issues/5762
The problem was only happening with a sort on a select type field, also
appears with currency type and maybe other types.
This was because NULL values were sorted in a random order because the
sort function was comparing two NULL values as not equal, so I just
added a case for when A === B === NULL.
