feat: add provisioner daemon name to provisioner jobs responses (#17877)

# Description

This PR adds the `worker_name` field to the provisioner jobs endpoint.

To achieve this, the following SQL query was updated:
-
`GetProvisionerJobsByOrganizationAndStatusWithQueuePositionAndProvisioner`

As a result, the `codersdk.ProvisionerJob` type, which represents the
provisioner job API response, was modified to include the new field.

**Notes:** 
* As mentioned in
[comment](https://github.com/coder/coder/pull/17877#discussion_r2093218206),
the `GetProvisionerJobsByIDsWithQueuePosition` query was not changed due
to load concerns. This means that for template and template version
endpoints, `worker_id` will still be returned, but `worker_name` will
not.
* Similar to `worker_id`, the `worker_name` is only present once a job
is assigned to a provisioner daemon. For jobs in a pending state (not
yet assigned), neither `worker_id` nor `worker_name` will be returned.

# Affected Endpoints

- `/organizations/{organization}/provisionerjobs`
- `/organizations/{organization}/provisionerjobs/{job}`

---

# Testing

- Added new tests verifying that both `worker_id` and `worker_name` are
returned once a provisioner job reaches the **succeeded** state.
- Existing tests covering state transitions and other logic remain
unchanged, as they test different scenarios.

# Front-end Changes
