fix(server): decouple SDK client generation from workspace activation (#20514)

`activateWorkspace` enqueues SDK gen job inside
`WorkspaceManagerService.init()` introduced by
https://github.com/twentyhq/twenty/pull/19271

But if enqueue call fails it crashes cuz it doesn't have try catch so
created workspace is in corrupted state

FIx:
Move SDK enqueue out of `init()` Call after
`activateAndInitializeUpgradeState` succeeds, wrap in try catch. Mirror
preInstalledAppsService.installOnWorkspace pattern.

Assuming enqueue failure if Redis is unavailable we fallback to
`SdkClientArchiveService.downloadArchiveBufferOrGenerate` which
generates it on the fly

Around 19 workspaces in prod affected with status `ONGOING_CREATION`
