* feat(import): stream real Arcim migration progress as NDJSON (#1485)
* feat(import): stream real Arcim migration progress as NDJSON
The /migrate route ran the orchestrator to completion and answered with one
JSON blob, so the wizard faked its progress bar: a hardcoded 55% anchor and
a static step label for a phase that can take minutes. The orchestrator has
had a real onProgress channel (eight emit points with Swedish step labels
and anchors) since it was written; the route just never passed it.
Now a request with Accept: application/x-ndjson gets a streamed response:
one line per orchestrator progress event, then a terminal done line with
the results or an error line carrying the same structured envelope the
JSON path returns (the 200 status is already committed once the stream
opens). Callers without the header keep the original single-JSON contract,
so pre-deploy tabs and the existing error-mapping tests are untouched.
The wizard opts in, drives MigratingStep from the real labels and anchors
(mapped onto the 55-100 slice of the wizard bar), and treats a dropped
connection as unconfirmed rather than failed, since the migration keeps
running server-side and a blind retry could double-import.

* feat(import): mount the knowledge-graph theater on the Arcim migrating step
The migration wizard already holds the fully parsed SIE client-side
(SIEData.parsed from /sie-data), so the same TheaterCanvas that carries
the /import flow can build the company's knowledge graph while the
migration runs: no server change, and the plain progress card stays as
the fallback whenever no parsed SIE exists (e.g. providers without SIE).
Unlike /import's fixed narration script, the wizard knows exactly what
the server is doing: phase 1 posts one SIE file at a time and phase 2
streams the orchestrator's real progress events. ArcimMigrationTheater
therefore narrates by printing those real step labels once each as they
arrive, and keys the canvas to the same milestones: the GL skeleton
(rings, buckets, accounts) builds during the journal writes, counterparty
waves attach while customers and suppliers import, and reconciliation
pulses. Real progress bar and elapsed counter stay visible throughout.

* fix(import): review fixes on the migration theater and stream close
CodeRabbit on #1486: (1) the aria-live region wrapped the per-second
elapsed counter, so a screen reader re-announced the timer every second
and drowned out the real step labels; the live region now covers only the
narration list and the timer row is aria-hidden (the Progress bar exposes
its own ARIA value). (2) controller.close() in the stream's finally block
throws if the reader already cancelled, escaping start() as an unhandled
rejection; now guarded like send().
