Console polish found while repairing a NodeLink store

Found while running Task 6677 (Repair on prod store `fs-02769ebfe9f7010b7`): 1. **Repair policy gives no feedback on success.** The Storage tab looks the same after the click. Show a short success line, e.g. "Policy rewritten · N access points". 2. **The console never shows the file-system policy.** To verify a Repair, you have to read AWS directly. Add a read-only view of the live policy on the store's Storage tab (Refresh from AWS can fetch it). 3. **An operator cannot find a tenant's store by file-system id.** With "All orgs" selected, Machines → NodeLink lists only the operator org's NodeLinks. Finding Cisne's store needed EFS tags plus Customers → Act as. List tenants' NodeLinks or stores with their fs id for operators, or add a search by fs id. 4. **The NodeLink row's Storage column shows the store name only.** Add the file-system id so the row matches what AWS findings report. Out of scope: policy contents, provisioning, mount behaviour. Done means: - Each item ships, or is explicitly declined with a reason. - The rendered surfaces are checked at desktop width.

All 4 shipped: Repair success line (N access points), live read-only policy view, operator all-orgs NodeLink list with Org column + fs-id search/Act as, fs id in Storage column. Full gate green; PR #5624 merged; desktop visual check good. Follow-ups: draft 6699.
