## Context
The generic "create a record" UI affordance previously required
`!isSystem`, conflating two distinct concerns: **"hidden from Data
Model"** and **"not user-creatable"**. This blocked legitimately
creatable system objects (e.g. marketing message lists kept `isSystem:
true` only to stay out of the Data Model).
This PR makes creatability depend on `isUICreatable` alone, so
visibility (`isSystem`) and creatability (`isUICreatable`) become
independent.
## Changes
- **Front gate** (`canCreateRecordsForObjectMetadataItem.ts`): drop the
`!isSystem` clause — creatability is now `isUICreatable && !readOnly`.
Updated comment + unit test.
- **Command menu** (`standard-command-menu-item.constant.ts`): drop the
matching `not objectMetadataItem.isSystem` clause from the
`createNewRecord` availability expression so the "Create new X" command
mirrors the front gate. Existing workspaces get this via the
already-present `SyncCreateRecordCommandAvailabilityExpressionCommand`,
which re-syncs from the live definition.
- **Standard object audit**
(`create-standard-flat-object-metadata.util.ts`): the 15
sync/system-created standard objects that relied on `!isSystem` to stay
non-creatable now set `isUICreatable: false` (attachment, blocklist,
calendar*/message*/note/task targets, message, messageThread,
messageParticipant, timelineActivity, callRecording,
workflowAutomatedTrigger, …).
`workflowRun`/`workflowVersion`/`workspaceMember` were already `false`.
Non-system objects (company, person, note, opportunity, dashboard, task,
workflow) are untouched.
- **Backfill**: new fast instance command
(`2-13-…-1781277480000-backfill-non-ui-creatable-standard-system-objects.ts`)
runs `UPDATE core.objectMetadata SET isUICreatable = false` for those
standard system objects (symmetric `down`), registered in
`instance-commands.constant.ts`.
`isSystem` and Data-Model visibility logic are unchanged.
## Verification
- Front gate unit test (7 pass), standard-application suite incl.
callRecording (10 pass)
- `oxlint` clean on all changed files
- `twenty-server` and `twenty-front` typecheck green
