Replaces the alternating-side insertOnRight rule with a sort-and-splice
that places every loose spouse to the right of the parented focal in
(fromYear ASC NULLS LAST, displayName ASC) order. Mirrored in step 3 for
the all-loose chained merge so Albert de Gruyter's four marriages land
in deterministic alphabetical order today (no fromYear populated in the
canonical dataset) and switch automatically to year-order as the
transcription pipeline backfills marriage years.
PersonNodeDTO carries only displayName, not parsed first/last names, so
the tiebreaker uses displayName rather than the (lastName, firstName)
key in the original UX brief. The canonical alphabetical order matches
in both schemes — the rule activates the moment a multi-spouse case has
mixed display-name patterns.
Retires the temporary commit-3 scaffold
`attaches_loose_multi_spouse_to_parented_partner_when_edge_order_clobbers`
which became position-arithmetic-equivalent under the new right-of-focal
rule; the two new sort tests are stronger discriminators for the same
behaviour.

Switches spousePairs from Map<string, string> to Map<string, Set<string>>
so multi-spouse persons (canonical case: Albert de Gruyter, 4 marriages)
keep every partner instead of losing the earlier .set() values.
The behavioural discriminator (now exercised by
attaches_loose_multi_spouse_to_parented_partner_when_edge_order_clobbers)
is a loose person with both a parented and a loose spouse: the old map
clobbered to whichever edge landed last, so the loose-placement step could
miss the parented partner and merge the focal node into the wrong block.
Also closes the robustness gap NullX flagged: SPOUSE_OF edges referencing
IDs outside allNodes are dropped at ingestion instead of leaking into the
spouse-pulldown loop.

buildLayout switches to a two-stage assignment:
1. Seed — every node with node.generation != null is locked at that
rank. The fallback heuristic never moves a locked rank, and the
spouse-pulldown never pulls a locked rank.
2. Fallback — for unseeded nodes, rank = max(parent rank) + 1 reading
parents from the same unified rank map, so an unseeded child of a
seeded G 2 parent correctly inherits rank 3. Spouse-pulldown ties
unseeded spouses to their deeper partner exactly as before.
3. Normalise — if any rank is negative (future G −1 ancestor), shift
the whole map so min(rank) == 0. No-op for today's data.
Fixes the Herbert Cram pattern from #361's review: two parented
spouses with imported G 3 now render on the same y row. Existing
StammbaumTree tests still pass byte-for-byte because every test node
has node.generation undefined, so the heuristic runs unchanged.

Move the layout function out of StammbaumTree.svelte (lines 47-275) into a
new pure TypeScript module at frontend/src/lib/person/genealogy/layout/
buildLayout.ts so it can be exercised by direct unit tests. Drops the
eslint-disable svelte/prefer-svelte-reactivity blanket; switches the
remaining scope-local Maps/Sets in parentLinks to SvelteMap/SvelteSet to
satisfy the rule per-call-site. No behaviour change — existing
StammbaumTree tests must pass byte-for-byte.
