## What
The integration test
`failing-app-installation-workspace-version.integration-spec.ts` is
flaky depending on the shape of the upgrade sequence, especially right
after a version bump. It intermittently fails at upload time with:
```
App requires Twenty server >=2.21.0 but this server is 2.20.0.
(SERVER_VERSION_INCOMPATIBLE)
```
## Why
The test mixed two different version sources:
- The upload-time check (`validateServerCompatibility`) compares the
app's required version against the **instance** inferred version, i.e.
the last attempted instance command (`workspaceId IS NULL`, via
`getInferredVersion`).
- The test's `beforeAll` instead derived the required version from the
**workspace** cursor.
These agree most of the time but diverge right after a version bump
whose newest upgrade segment ends in workspace-scoped commands and adds
no new instance command. In that state the seeded workspace cursor sits
at the new version while the instance is still at the previous one. The
test then uploads an app requiring `>=newVersion`, which fails the
instance gate at upload time before the workspace gate under test is
ever reached.
## How
Derive the gate version in `beforeAll` from the last attempted instance
command, mirroring exactly what `getInferredVersion()` uses. The
required version is then always `>=` the instance's own version, so the
upload passes; injecting that same command as a failed workspace attempt
drops the workspace to the previous completed version, so the install
reliably hits the workspace gate and returns
`WORKSPACE_VERSION_INCOMPATIBLE` as the snapshot expects. This holds
regardless of whether the newest version's segment ends in an instance
or workspace command.
No production code changed; the fix is confined to test setup logic.
