carsten acaa2383e9 Add admin CRUD for purchase rounds and wine offerings, with round copy
Full CRUD on PurchaseRound and WineOffering, org-scoped via two new
join-based dependencies.py helpers (get_round_in_organization,
get_wine_offering_in_organization) mirroring task 5's pattern. New
rounds always start as draft regardless of what the client posts,
avoiding a confusing creation-time constraint error.

POST /purchase-rounds/{id}/copy implements "kopiér fra forrige runde":
duplicates every round field (dates, texts) and every wine offering
(incl. category) into a fresh draft, leaving the source untouched.

PurchaseRound DELETE gets a three-tier policy based on status: draft
deletable by any admin, open never deletable, closed only by an
elevated superadmin. This is runtime-conditional on the loaded row, so
the elevation check was extracted out of get_current_active_superuser
into a standalone require_elevated_superuser(user, token) helper that
both the dependency and this handler call directly. WineOffering
delete has no such tier — an offering with real order lines is already
blocked by the existing RESTRICT FK, caught here as a 409.

Also seeds the 8 wine categories (empty table blocked any offering
creation) via a plain Alembic data migration, idempotent and
unconditional (no secret involved, unlike the task-4 superuser seed).

Verified end-to-end: dates-required 409, open round successfully
patched with dates, wine offerings created, round copied (new draft,
duplicated offerings with new ids/same category), open-round delete
403, closed-round delete 403 then 204 after /auth/elevate, wine
offering delete 204, draft round delete 204 (cascades its remaining
offering). DB left clean, participant count unaffected.
