docs: drop stale MassImportService/ODS references from import deploy docs

The mass-import card no longer parses an ODS spreadsheet and MassImportService
was deleted (#674); /import now holds the normalizer's canonical artifacts
(canonical-*.xlsx + canonical-persons-tree.json) plus <index>.pdf files, read
by the canonical importer. Fix the IMPORT_HOST_DIR descriptions in
DEPLOYMENT.md and docker-compose.prod.yml accordingly.

 Entity: `Tag` (self-referencing `parent_id` tree).
 Features: tag CRUD, hierarchical deletion (cascade to descendants), tag typeahead, admin tag management (rename, reparent, merge).
 
-## Tag tree counts (`getTagTree`)
-
-`GET /api/tags/tree` returns each node with **two** document counts, from two aggregate queries (no N+1):
-
-- `documentCount` — documents tagged with that **exact** tag (direct). Read by the admin surfaces (sidebar tree, merge preview, delete-impact guard), which describe direct-document operations.
-- `subtreeDocumentCount` — **distinct** documents tagged with that tag **or any descendant** (subtree rollup, recursive-CTE closure, depth guard ≤50). Read by the reader surfaces (`/themen` page, dashboard `ThemenWidget`) so the box number matches what `/documents?tag=X` actually finds.
-
 ## What this domain does NOT own
 
 - Documents — the `document_tags` join table is on the document side. `Tag` does not hold document references.
