test(portal-clis): isolate valid flag controls from live services (#581)

* test(portal-clis): isolate valid flag controls from live services

The LinkedIn and Freehire positive controls spawned live search CLIs and only checked for the absence of BAD_ARG, so attempted portal requests still left a green suite. Use loopback responses and assert successful output plus the constructed freshness, pagination and result-limit contract.

LinkedIn cards are verbatim excerpts from portapulito's actual captured response in PR #153; fixture provenance and original hashes are retained. Four Danish validation suites already stop at required-argument guards and need no change. This isolates these controls rather than claiming a whole-CI egress policy.

* docs(changelog): record fix for #581

+# Offline search cards
+
+`search-cards.json` stores the HTML string for the first two verbatim `<li>` cards from a real
+LinkedIn guest search response captured by **portapulito** through the CLI's
+`htmlFetch` on 2026-07-14 and published in [PR #153](https://github.com/MadsLorentzen/ai-job-search/pull/153).
+That PR was closed as an accidental personalized-fork submission, not merged.
+
+Source: `.agents/skills/linkedin-search/cli/test/__fixtures__/search-list.html`
+at commit `5bc3afb94d19b670ecf09287c20d0c95e5d13ba0`.
+Original response SHA-256: `ff5fb9009f26c8f602b1ac4b018f471e76784300723b22db64d9d19c2b7f557c`.
+Two-card excerpt SHA-256: `1ab95e6ccb38b50d922e4d714ff95bb58219c012489a3a94aca5e0adb7b552fb`.
+
+The JSON string encoding preserves the original HTML whitespace without adding
+trailing whitespace to source lines. The excerpt hash above is of the decoded HTML.
+
+The valid-flag controls serve these saved cards over loopback HTTP. Their child
+CLI preload accepts only the expected search endpoint and redirects that request
+to loopback. Tests assert the actual URL parameters, successful output, IDs and
+client-side result limits. No fixture regeneration or portal request occurs.
+This isolates these controls; it is not an OS-level egress policy for the entire CI.
