feat(sentry): propagate workspace context to all spans (#20064)

## Summary

After the 2026-04-26 token-usage incident, identifying the responsible
workspace from a Sentry trace required a Postgres scavenger hunt —
Vercel AI SDK auto-instrumentation captures token counts and model name
but no twenty-specific identifiers, and that same gap exists for every
other auto-instrumented span (HTTP outbound, Postgres queries, GraphQL
resolvers, Redis, etc.).

This PR plugs that gap globally, not just for AI:

- A small utility
(`packages/twenty-server/src/engine/core-modules/sentry/utils/sentry-workspace-context.util.ts`)
that writes workspace identifiers onto Sentry's active isolation scope
as a `twenty` context block plus filterable tags and a `Sentry.setUser`
call.
- Two hook points covering all server traffic:
- **`WorkspaceAuthContextMiddleware`** — already runs after token
hydration on the GraphQL, metadata, admin-panel, and REST routes. It now
calls the utility once per authenticated request, before delegating to
`withWorkspaceAuthContext`.
- **`BullMQDriver.work` and `SyncDriver.processJob`** — every queue job
now runs inside `Sentry.withIsolationScope` and applies workspace
context from `job.data.workspaceId` (skipping silently for system jobs
that don't carry one).
- A `beforeSendSpan` hook in `instrument.ts` that reads the scope's
`twenty` context block back and projects it onto every span as
`twenty.workspace.id` and (when available) `twenty.user_workspace.id` —
dotted-namespace naming consistent with OTel/Sentry conventions like
`user.id` and `http.response.status_code`. Spans without a workspace
context (unauthenticated traffic) pass through untouched.

## Why this shape

Sentry's docs position `beforeSendSpan` as a per-span hook. The previous
iteration set context only at AI-specific call sites, which left non-AI
spans (DB queries, outbound HTTP, regular GraphQL queries, workflow
steps not touching AI) entirely unenriched. Hooking the two existing
global boundaries — auth middleware for HTTP/GraphQL/REST, and the queue
driver `work()` callback for background jobs — covers every
authenticated span across the app with no per-handler instrumentation.

## What's not in this PR

AI-specific identifiers (`twenty.agent.id`, `twenty.thread.id`,
`twenty.turn.id`, `twenty.workflow_run.id`) are out of scope here.
They're useful additions but require either propagating the IDs through
the call stack or a more fine-grained scope (per-step, per-turn) than
the request/job boundary, which is best handled in follow-up PRs that
target those specific call sites.

## Test plan

- [ ] Make any authenticated GraphQL request locally and confirm the
resulting span(s) in Sentry carry `twenty.workspace.id` and (for
user-authenticated routes) `twenty.user_workspace.id`.
- [ ] Make any authenticated REST request and confirm the same.
- [ ] Trigger a queue job (chat stream, agent turn evaluation, workflow
run, etc.) and confirm spans produced inside the worker carry
`twenty.workspace.id`.
- [ ] Confirm that DB and outbound HTTP spans produced under the
request/job also carry the workspace tag — these previously had no
twenty-specific identifiers.
- [ ] In the Sentry UI, filter events by the `twenty.workspace.id` tag
and confirm matching events appear.

## Notes for review

- Sentry init lives in `instrument.ts`, loaded before Nest bootstraps,
so `beforeSendSpan` runs outside Nest DI and reads context off the
isolation scope rather than holding a service reference.
- The middleware change is three lines; the BullMQ wrap is a single
`Sentry.withIsolationScope` around the existing job handler body; the
SyncDriver wrap mirrors it for the dev/test path. No new modules or DI
providers.
- The previous iteration's `AiCallContextService` and per-handler
`setContext` / `withContext` calls have been removed in favor of these
two hooks.
