No fixture seed, no event host, and the edit affordance stops lying

Three changes the product model asked for.

The fixture seed no longer writes anything into a connected wallet, by any
route. `bootstrapWallet` is the single enforcement point -- both call sites
funnel through it -- so the switch cannot be walked around by a screen or a
bridge. The fixtures, the seeding code, the demo path and the rendering tests
are untouched; a unit test now fails if a document is created after all.

An event has no host. The domain says so -- the meeting point has a host, the
event is only the anchor -- while the shape carried `hostName`/`hostInitials`
and every created event was written with the fabricated `'Moi'` / `'MD'`. Gone
from the shape, the ORM bindings, the type, the adapters, the writes and the
screens. `fp:MeetingPoint.host` stays: that one is real.

Regenerating the ORM revealed the committed bindings had drifted from what the
generator emits -- stylistic, verified predicate by predicate, plus the loss of
the `Fp` prefix. The prefix cannot be restored at the generator: the name comes
from the shape IRI, and those IRIs are the persisted RDF classes. Aliased at the
three import sites instead, so nothing downstream moved and the DOM `Event` and
`Notification` types are never shadowed.

Write rights are ownership, read from the list
The contract leaves no other reading -- only an owner writes, and no call adds a
writer -- so `listMyEntityDocs('public')` is what says which events are mine.
The hard-coded `isOwner = true` is replaced by a three-state answer, and the
UNKNOWN state renders neither a pencil nor a greyed one: a disabled look-alike
invites a dead click.

Two adversarial passes refuted the first attempt and both defects are fixed. A
latched boolean denied an owner their own event forever once a listing had
missed it; the ruling is now rebuilt rather than accumulated, so a later listing
overturns an earlier one.

Residual, deliberate and commented: "not mine" is inferred from absence, and the
reactive read and the listing are separate mechanisms, so a freshly arrived
event is ruled out for the window between them. Closing it needs a timer, which
the doctrine forbids.
