renameFolder + moveFolder enforce sibling-name uniqueness via the
shared isSiblingNameConflict helper and reject cross-port leakage at
the service boundary. moveFolder walks the destination's ancestor
chain to refuse cycles before the write.
deleteFolderSoftRescue re-parents every child folder and document up
to the deleted folder's parent (or to root) inside a transaction,
then drops the folder row. Children never disappear silently — a
wrong click moves work up the tree, never deletes it. Audit-logged
with rescuedTo metadata.

Code-review followups on 4b31f01:
- beforeEach now scopes the documentFolders cleanup to the test port
via .where(eq(documentFolders.portId, portId)) so parallel suites
don't wipe each other's fixtures.
- Cross-port parent guard message changed from "Parent folder not
found in this port" (read like a 404) to "Invalid parent folder"
to match the ValidationError type that already maps to 400.

In-memory tree build (single SELECT + JS nesting); the folder tree is
small enough that a recursive CTE buys nothing. Sibling-name conflict
maps the Postgres unique-index 23505 to a typed ConflictError so the
UI can render a clean toast. Cross-port parentId rejected at the
service boundary. Also adds document_folders to the global teardown
CTE so test ports can be cleaned up without FK violations.
