Scope the Finland docs to the domestic network and open them to suppliers anywhere

[rilla]

Context

Finland consolidation picks up the follow-up work carried over after Finvoice went live.

Two things were wrong on the Finland pages. They said the app covers both of Finland's e-invoicing networks and that you should use it for every Finnish receiver — it delivers on the domestic operator network, and Peppol routing is the Peppol app's job. And they assumed every supplier is Finnish, which gov-fi#20 changes: a company established anywhere can now register and invoice Finnish receivers through the same operator, workflows and formats. Those parties can send but not receive — a Finnish e-invoice address belongs to a Finnish Business ID, so a company established elsewhere is never listed in the national registry and nothing reaches it over the domestic network. They receive through Peppol instead.

This should merge once the app change ships.

Changes

• Scopes the Finland pages to the domestic operator network — the app page's description, intro, feature bullet and Limitations delivery row; the issuing guide's introduction; and the compliance FAQ, which answered "no" to whether you have to choose between the domestic network and Peppol and now answers yes. Left standing: that Finland runs two networks and that verkkolaskuosoite.fi lists both, which is what tells a reader which app they need.
• Adds a "Suppliers outside Finland" section to the supplier registration guide — that any country can register, what the operator files the party under, that registration is send-only and why, and where to register for receiving instead.
• Notes the foreign supplier on the Finland app page, under the supplier document description.
• Qualifies the Finland-only statements the new case breaks — the Business ID prerequisite, the reception-workflow prerequisite, the completion text that promised an allocated address and polling for every party, the rule to always use an OVT address on party records, and the "Register party in Finland" action card.
• Limits reception to Finnish parties in the receiving guide and its FAQ. Both said every registered party's inbox is polled. They now say reception covers Finnish parties, and point parties from elsewhere to the Peppol app.
• Corrects two Finland claims outside the app pages. The Finland timeline listed the domestic network as roadmap, and now shows it covered by the Finland app. The Europe overview grouped Finland with the Peppol-first countries. It now says Peppol serves public bodies and most businesses receive on the domestic network.
• Updates the registration workflow's description to cover parties from any country, in step with the console template, and asks a foreign supplier for its own address, not a Finnish one.
• Rewrites the new text in plainer words, following Luis's review. Sentences are shorter and the facts are unchanged.

Verification

Done:

• Read back against the shipped behaviour in gov-fi#20: what a foreign party is filed under, and what it can and cannot do once registered.
• Mintlify deployment and link-rot checks pass.

Left:

• Preview the Finland app page, the three guides, the Finland timeline and the Europe overview, checking the #suppliers-outside-finland anchor resolves from the prerequisites bullet and the app page.

• The app change: gov-fi#20
• The registration template's description is rewritten to match console#319. The Finland templates are .mdx, which the console sync doesn't pick up, so the docs copy is kept in step by hand.

Looks good to me for a 1st pass, maybe the AI agent can polish a bit more the text here so it looks less AI generated
