## Summary
- Adds a new admin action to move a subscription (and Stripe customerId)
from one organisation to another owned by the same user
- The target organisation must be on the free plan (no active
subscription) — enforces paid → free only
- The source organisation's claim is reset to the free plan after the
move
## How it works
A "Move Subscription" option appears in the actions dropdown of the
organisations table (on the admin user detail page) for any org with an
active or past-due subscription. Clicking it opens a dialog where the
admin selects a target org from a filtered list of eligible (free-plan)
orgs owned by the same user.
The backend performs the swap atomically in a single Prisma transaction:
1. Deletes any stale inactive subscription on the target org
2. Moves the `customerId` from source to target org
3. Reassigns the `Subscription` record to the target org
4. Copies claim entitlements to the target org
5. Resets the source org's claim to FREE
No Stripe API calls are made — the Stripe subscription and customer
remain unchanged; only the DB-level org association is updated.

Replace use() with useEffect/useState pattern to prevent 'async Client
Component' errors in Next.js 16 / React 19. Also strip colons from
useId() output which broke mermaid's render().
## Description
Resolves an issue where individual plan customers who cancel are not
correctly put down to the free plan.
To resolve this, we delete the subscription on the stripe subscription
delete webhook. Since the customerId is stored on the organisation they
can still access their old invoices.
