docs(client): align three organization docblocks with the decoded metadata wire

Round-2 contract-review fix for #18728 (PR #19122, FAIL — scoped, comment
5736639314). OrganizationWire's docblock at :1206-1213 was rewritten to say
metadata arrives DECODED on setActive/get/delete/list, but three linked
docblocks on the same published SDK surface still declared the old stored-
JSON-text wire: OrganizationFullWire, organizations.setActive and
organizations.get. Each is corrected to point at OrganizationWire and state
the one now-true fact, without repeating the block itself.

Also clarifies organizations.delete's "as it was stored" phrase, which is
ambiguous rather than wrong (it is about which row — the pre-delete
snapshot — not about metadata encoding) on a route this PR now decodes.

Prose only: no type, export or runtime change.
