docs: one explanation of how to get Maskinporten access, used everywhere

[erlendoksvoll]

Follow-up to the question of where to reference Digdir's "forenklet onboarding til Maskinporten". The pilot itself (onboarding.maskinporten.no) is offline and its repository is gone, so it is not linked; what this PR carries over is the concept: a consumer does not need a virksomhetssertifikat, and test access needs only the lightest Altinn right.

New shortcode maskinporten-tilgang (layouts/shortcodes/): the five steps a consumer goes through, kept in one place. Parameters scope, produkt, and an optional tildeling text for services where scopes are pre-assigned or need an external approval first. A note in the template says where to mention the pilot if Digdir revives it.

Pages

• Kom i gang med API: rewritten "Autentisering og autorisasjon" intro and a new "Slik får du Maskinporten-tilgang" section using the shortcode. Step 3 of the overview points to it.
• Steg for steg, Testing, FAQ: link to that section. Testing explains why a test integration is quicker. New FAQ entry: "Må jeg ha virksomhetssertifikat for å bruke Maskinporten?"
• Advokatregisteret, BITS, Tilda (request examples): use the shortcode with their own scopes and rules instead of three slightly different paragraphs. Content facts (Advokattilsynet approval, BITS pre-assigned scopes, Tilda scope for all consumers) are kept.

Verified: scope names against the live metadata API (altinn:dataaltinnno/ebevis, /tilda, /kontrollinformasjon, /utleggspant; Advokatregisteret per dataset); Samarbeidsportalen steps and Altinn right names against docs.digdir.no's self-service guide.

Also replaces the deprecated .Site.Data with hugo.Data in the landing layout (Hugo 0.166 warns).

Walkthrough

The documentation adds reusable Maskinporten access instructions and updates general and service-specific scope guidance. The landing-page template also changes its data reference for landing groups.

Changes

Maskinporten access guidance

Layer / File(s)	Summary
Shared access instructions layouts/shortcodes/maskinporten-tilgang.html, content/api/_index.md	A shortcode provides five access steps and supports scope, assignment, and product parameters. The API guide distinguishes token authentication from API-key authorization and includes service scope guidance.
Setup and testing guidance content/api/steg-for-steg/_index.md, content/ofte-stilte-spørsmål/_index.md, content/testing/_index.md	The guides describe integration setup, test access requirements, key-pair use, separate test and production scope assignment, and links to Maskinporten access instructions.
Service-specific access instructions content/tjenester/advokatregisteret/_index.md, content/tjenester/bitskontrollinformasjon/_index.md, content/tjenester/tilsynsdata/eksempler/klientrequest.md	The service pages specify scope assignment and access instructions for Advokatregisteret, Bitskontrollinformasjon, and Tilsynsdata.

Landing-page data reference

Layer / File(s)	Summary
Landing-page group lookup layouts/index.html	The landing-page group loop now reads from hugo.Data.landing.groups.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to ac8bc

Test users may fail API calls when they follow the shared setup and use a production key. Add the test portal and clarify environment matching; the impact is limited to test onboarding.
