fix: route share-by-email link to correct dashboard path by type

[mengw15]

What changes were proposed in this PR?

ShareAccessComponent.grantAccess hard-coded the dashboard/user/workflow/ path segment when constructing the share-notification email's "access the ... at ..." URL, regardless of which resource type the dialog was opened for. Because the dialog is opened with type: "dataset" / type: "project" / type: "workflow" from the respective list-item components, the link in the email for shared datasets and shared projects pointed at the workflow route and 404'd on click.

Branch on this.type to pick the correct route from the existing app-routing.constant.ts constants:

• workflow → DASHBOARD_USER_WORKFLOW (/dashboard/user/workflow)
• dataset → DASHBOARD_USER_DATASET (/dashboard/user/dataset)
• project → DASHBOARD_USER_PROJECT (/dashboard/user/project)

computing-unit is unaffected — the existing if (this.type !== "computing-unit") guard already skips the URL line for that type.

Note: the issue mentioned the dataset case only; the project case has the same defect and is fixed by the same change.

Any related issues, documentation, discussions?

Closes #5163.

Follow-up to #4200 (which fixed the missing /dashboard/user/ prefix on the same line per #3583); this fixes the remaining hard-coded workflow segment.

How was this PR tested?

Added share-access.component.spec.ts (Vitest + TestBed + HttpClientTestingModule) with four cases that exercise grantAccess:

• type=workflow, id=11 → email message contains /dashboard/user/workflow/11
• type=dataset, id=22 → email message contains /dashboard/user/dataset/22
• type=project, id=33 → email message contains /dashboard/user/project/33
• type=computing-unit, id=44 → email message does NOT contain /dashboard/user/

Each case mocks the component's injected dependencies (ShareAccessService, UserService, GmailService, NotificationService, NzMessageService, NzModalService, NzModalRef, WorkflowPersistService, DatasetService, WorkflowActionService, NZ_MODAL_DATA), runs grantAccess, and inspects the message passed to gmailService.sendEmail to confirm the URL formatting.

Verified locally:

• yarn test --include='**/share-access.component.spec.ts' — 4 passed.
• yarn prettier --check src/app/dashboard/component/user/share-access/share-access.component.{ts,spec.ts} — clean.

Manual verification path:

1. Share a dataset via the dataset list dashboard, entering a real email address.
2. Check the recipient's inbox: the link should now read https://<host>/dashboard/user/dataset/<did> and resolve to the dataset detail page on click.
3. Repeat for a project: link is /dashboard/user/project/<pid>.
4. Repeat for a workflow: link is /dashboard/user/workflow/<wid> (unchanged behavior).
