Closes [89](https://github.com/twentyhq/core-team-issues/issues/89)
## Problem
When users attempt to create or update a record with a duplicate value
for a unique field (e.g., duplicate email or domain name), they receive
a generic error message: "This record already exists. Please check your
data and try again." This provides no actionable way to locate and view
the existing conflicting record, forcing users to manually search for
it.
## Solution
This PR enhances duplicate key constraint error handling to
automatically detect the conflicting record and display a "View existing
record" link in the error notification. When clicked, users are
navigated directly to the existing record's detail page.
## Backend Changes
### 1. PostgreSQL Error Parsing
(`parse-postgres-constraint-error.util.ts`)
- Extracts structured information from PostgreSQL `QueryFailedError`
messages.
### 2. Conflicting Record Lookup (`find-conflicting-record.util.ts`)
- Queries the database to find the existing record with the conflicting
value
### 3. Error Handling Orchestration
(`handle-duplicate-key-error.util.ts`)
- Parses PostgreSQL error to extract column name and conflicting value
- Attempts to find the conflicting record
- Enriches `TwentyORMException` with `conflictingRecordId` and
`conflictingObjectNameSingular` if found
### 4. Exception Computation Updates (`compute-twenty-orm-exception.ts`)
- Made function `async` and added optional `entityManager` and
`internalContext` parameters
- Needed to support async database queries for conflicting record lookup
### 5. GraphQL Error Handler
(`twenty-orm-graphql-api-exception-handler.util.ts`)
- **Changes**: Enhanced `DUPLICATE_ENTRY_DETECTED` case to include
`conflictingRecordId` and `conflictingObjectNameSingular` in GraphQL
error extensions
## Frontend Changes
### 1. Error Extraction Utility
(`get-conflicting-record-from-apollo-error.util.ts`)
- Accesses GraphQL error extensions
- Validates that both `conflictingRecordId` and
`conflictingObjectNameSingular` exist and are strings
- Returns `null` if validation fails
### 2. SnackBar Enhancement (`useSnackBar.ts`)
- Extracts conflicting record info from Apollo error
- Constructs URL using `getAppPath` utility
- Adds link object to snackbar options with text "View existing record"

## Context
Deprecating the old objectMetadataMap type in favour of split flat
entities to match with our new caching.
In the long run, trying to achieve:
- Better performance through caching
- Consistent data access patterns across the codebase
- Reduced database queries
Now that everything is based on flat entities, which are cached, we can
finish the refactoring of workspace context cache which should already
improve performances.
Then the last step will be to consume that new cache in the new global
datasource to get rid of the many workspace datasources stored in the
server
In this PR:
- adding a try / catch around all ORM internal methods save, insert,
upsert, findOne, ...
- leveraging this error to prevent messageChannels to get FAILED
- optimizing messaging BATCH_SIZE and THROTTLE threshold according to
local tests
