Replace documents page with Resumier microfrontend embed

[adriandarian]

Motivation

• Replace the large, standalone Documents page implementation with an embeddable Resumier microfrontend to simplify demos and enable a shared Prosperis app experience.
• Allow the Resumier app to run standalone for development while being embedded in THRIVE for production demos via a configurable URL.
• Keep the integration lightweight and non-invasive so THRIVE's existing document stores and migrations are not changed in this PR.

Description

• The /documents route now renders a new ResumierMicrofrontend component instead of the original Documents page logic by replacing src/routes/documents.tsx to return <ResumierMicrofrontend />.
• Added src/components/features/documents/ResumierMicrofrontend.tsx which loads the microfrontend from the VITE_RESUMIER_URL env var and shows a helpful fallback message when the URL is not set.
• Added the integration proposal document at docs/proposals/resumier-microfrontend.md that describes the embed approach, rollout plan, and open questions.
• The change removes the previous Documents page implementation (large deletions) and leaves a single iframe-based integration point to be iterated on later.

Testing

• No automated tests were run for this change (none requested during the rollout).

Forward document selection into embed URL

The iframe src is always just VITE_RESUMIER_URL, so any document-selection context in the parent URL is dropped. Other parts of the app still navigate to /documents with a docId query (e.g., LinkedDocumentsPopover uses navigate({ to: '/documents', search: { docId } })), which previously opened a specific document. With the new embed, that docId never reaches Resumier, so clicking “View document” from an application will no longer open the intended document. Consider appending window.location.search (or a docId param) to the iframe src, or using postMessage, so the microfrontend can preserve this deep-link behavior.
