Summary

• Add cursor-backed pagination for workspace-scoped and platform sandbox lists and workspace lists, with label selectors forwarded to the gateway.
• Add an execution-environment type-label filter and page-aware selection in the UI.
• Preserve the legacy array response when pageSize is absent; paged requests return items and nextPageToken.
• Limit workspace draft-summary reads to visible sandbox names on paged lists.

Ticket: RHOAIENG-98858

The ticket describes limit and offset, but the pinned OpenShell Go SDK exposes PageSize and opaque PageToken in ListOptions. This PR uses that upstream cursor contract rather than inventing an offset layer.

Verification

• Frontend lint and Prettier check: passed
• Frontend typecheck: passed
• Frontend Jest: 115 suites, 2,058 tests passed
• Stubbed Cypress UI suite: 6 specs, 46 tests passed in Chrome
• Go vet and go test ./...: passed
• git diff --check: passed

The local gateway compatibility suite was not run because the Docker daemon is unavailable in this environment. CI should verify the real gateway contract. The make lint target reached its Go lint step, but golangci-lint is not installed locally; go vet ./... passed.

Nice — pagination is genuinely server-side and stays relay-only (forwards the SDK Pager / opaque PageToken, and keeps the legacy array when pageSize is absent). Two things required before merge:

1. Rebase onto main and move to the 0.1.5 SDK. The branch is on the pre-0.1.5 SDK and conflicts with fix: move to OpenShell 0.1.5 #118. The Create mocks here still use the removed CreateOptions struct / positional labels, so a straight conflict resolution won't compile — take main's functional CreateOption signatures and layer your listPageFn changes on top (your List additions themselves aren't affected by the Create break).
2. Re-run CI after the rebase. The current green checks were built on the pre-0.1.5 base, so they don't prove 0.1.5 compatibility — please confirm build, check-backend, and compat (-count=1) are green on the rebased branch.

No rush on timing — this is tracked for 3.7 (RHOAIENG-98858), so it doesn't need to beat the 3.6 freeze.

Heads-up: I rebased this branch onto main (now with #124 and the e2e CI fix) and force-pushed it (7aafa70 → 5b95b7f).

• The only conflict was the import block in frontend/src/api/sandboxes.ts; I kept both sides.
• Add live logs streaming #124 added a second parameter to services.NewSandboxService, so list_pagination_test.go stopped compiling. I added a one-line fix commit (5b95b7f) that passes nil, like the other handler tests.
• Build, vet, Go tests, typecheck, lint and Jest pass locally.

Before you push again, reset your local branch:
