Address review nit: the older getTagTree tests relied on Mockito's default
empty-list return for findSubtreeDocumentCountsPerTag. Stub it explicitly so
the two-query contract is self-documenting.

Characterization tests for AC#8: the merge preview and the delete-impact
warning describe direct-document operations, so they must report the tag's
direct documentCount, never a subtree rollup. Both tests pass a stray
subtreeDocumentCount and assert it does not leak into the preview, so a future
change can't silently desync a destructive-action preview.

TagTreeNodeDTO now requires subtreeDocumentCount, so the admin sidebar test
fixtures (TagTreeNode, TagsListPanel) need the field to type-check. The admin
sidebar still renders the direct documentCount — these fixtures only gain the
new field, no behaviour change.

The /themen page (box header, child rows, aria-labels) and the dashboard
ThemenWidget now display subtreeDocumentCount instead of the direct
documentCount, so a topic's number reflects its whole sub-topic tree and
matches what /documents?tag=X actually returns. A parent with 0 direct
documents but documents under its children now shows a non-zero total.

Regenerate the TagTreeNodeDTO type with subtreeDocumentCount and switch
hasAnyDocuments to read it directly — the backend rollup already includes all
descendants, so the recursive children walk is no longer needed. Reader
surfaces now hide a topic only when its whole subtree is empty.

Record that getTagTree returns both documentCount (direct, read by admin
surfaces) and subtreeDocumentCount (rollup, read by the reader surfaces),
matching the corrected getTagTree JavaDoc.

Cover AC#1-4 (leaf=direct, distinct overlap counted once, full descendant
depth), REQ-THEMEN-05 (empty subtree absent), REQ-THEMEN-06 (cycle terminates
via the 50-level guard) and AC#7 (rollup equals distinct documents found by the
real tag-search expansion — count↔destination parity). Testcontainers
postgres:16-alpine since the recursive CTE + COUNT(DISTINCT) needs real PG.

Add subtreeDocumentCount to TagTreeNodeDTO, populated by a new recursive-CTE
aggregate query that builds a tag closure and counts distinct documents per
ancestor subtree. The direct documentCount is unchanged; getTagTree now maps
both counts onto each node from two aggregate queries (no N+1).
