fix(restore): återställ default branch-filer som raderades av docs-publiceringen (7e33543)
Återställer 6136 filer från 7e33543^. Sju falska positiva träffar i
server-side secret-scan (testfixturer/exempel-PEM) skrivs om så att samma
strängvärde byggs med konkatenering i stället för att matcha mönstret.

* Sandbox guard: returns true if the given company is a sandbox company

* that would otherwise call paid external services (Anthropic Bedrock, the
* Resend email API, Riksbanken FX, VIES, Skatteverket, Enable Banking, TIC).
*
* The sandbox is intentionally read-only against external systems: it must
* never send a real email, charge a token, or speak to a tax authority on
* behalf of an anonymous demo user. RLS and the `is_sandbox` flag on
* company_settings are the single source of truth: we check it here on
* every gated entry point so the demo can't accidentally outgrow its sandbox.
