Split the fleet roster from per-endpoint reads, and stop offering controls nobody can use
Twelve endpoints routes shared one permission, which made a reasonable policy
impossible to express. A site that wants signed-out visitors to see live status
on a PC page had to hand them the entire fleet - including every logged-in
username on the floor - because the per-asset panels and the fleet-wide list
were gated on the same string.

endpoints.fleet now gates the list and the three dashboard routes.
endpoints.view keeps the per-asset reads: status, services, processes,
interfaces, events, command history.

The name is load-bearing. guest_grantable_permissions() opens any '.view' or
'.read' permission to the guest role, so calling this one 'endpoints.fleet'
rather than 'endpoints.fleetview' is what keeps the roster off the public
surface while per-asset telemetry stays grantable. Verified both ways.

Also: the services panel emitted Start/Stop row actions to every reader,
because row_actions_for() never consulted the caller. Clicking was always
refused server-side, so nothing was exploitable, but showing a read-only viewer
controls over a shop-floor PC is the wrong signal - and it stops being cosmetic
the moment a site grants that panel to guests.

That needed a contract addition rather than a local check: caller_holds() on
shopdb.api answers whether THIS caller holds a permission without refusing the
request, which is the complement to require_permission for a surface that
serves everyone but should only offer what the caller can act on. Guests are
included, since a signed-out visitor holds whatever the guest role was granted.
Reaching into shopdb.utils.authz instead would repeat the ADR-002 violation the
contract gate caught earlier in this branch. Contract 0.24.0 -> 0.25.0.

DEPLOYMENT: endpoints.fleet is a new permission. Run 'flask seed permissions'
and grant it to the roles that should keep seeing the Fleet page. Until then
that page is admin-only, since admins bypass every check - a safe direction,
but not an automatic one.

Full suite 2124 passed, naming and contract gates green, map and spec
regenerated.

"""Endpoints plugin main class.
Endpoint RMM telemetry reported by the ShopDB agent. Accepts collector input
over HTTPS per ADR-006: the agent posts a per-host payload to
POST /api/collector/endpoints, the plugin resolves the reported hostname to an
existing computer asset, overwrites that asset's cached EndpointState, and
appends any curated Windows events the report carried - all in one commit, so
the cached snapshot and the events it summarizes never disagree.
Identity is the hostname, resolved against the computers plugin. An unresolved
hostname is reported as a ValueError (surfaced to the caller as a validation
error), never silently dropped: an unknown host is a real gap between the fleet
and ShopDB, the same discipline the backups collector uses for machine numbers.
