Hosted Instances 2 - store + first consumer

[n-lark]

PR — store + first consumer

• pages/team/Instances.vue reads the store via ensureTeamInstancesLoaded(teamId) behind a Page Loader; drop local list + status re-fetch. Keep the polling fallback when !live-status.live.

• Route create/delete + lifecycle through the store (upsert/remove, optimistic reconciled) — fixes the same-session bug.

• Store + vitest tests.

• Table reads store behind a Page Loader; polling fallback preserved.

• Optimistic reconciled in the store, not the mixin.

• Status via the join getter, not re-fetched.

8079 — Hosted Instances store + first consumer — test plan

✅ All tests passed!

Table load & empty states

• Cold load team Instances → data-table skeleton, then rows render from the store.
• Empty team (no instances, no filter) → "Get Started" empty state.

Pagination / search / sort / filter (server-side, still works post-migration)

• Page forward/back → each page fetches and renders; total + pagination controls correct.
• Search by name → debounced re-query, resets to page 1.
• Sort a column → re-query, order matches server.
• Status filter (running / error / stopped) → re-query; ?status= syncs to the URL; reload restores it.
• Rapid search/paging → no stale page flashes and the loader never sticks (abort works).

Lifecycle (optimistic in the store → reconcile)

• Start / Restart → row shows the optimistic spinner immediately, then reconciles to the real state via live-status.
• Suspend → confirm dialog → optimistic → reconcile; success/failure alert fires.
• Action API failure → row reverts to its prior state, warning alert.

Realtime & polling

• Server-side status change (MQTT live) → row updates in place, no reload, doesn't clobber an in-flight optimistic change.
• Kill MQTT → InstanceStatusPolling takes over; rows still update.

Delete

• Delete via kebab → confirm dialog → row disappears immediately + totals/backfill refresh (same-session fix).

Teardown (no stale / no leak)

• Switch team → list clears and reloads for the new team; none of the previous team's rows persist.
• Logout → log in as a different user → no previous user's instances.
• Navigate away and back (same team) → reloads fresh.
