CanaryTokens.tsx grows a Fleet/MazeNET toggle in the create modal. In
topology mode we hydrate /topologies?status=active for the topology
picker, then GET /topologies/{id} on selection to repopulate the decky
picker — topology deckies have a different shape than fleet's /deckies
endpoint.
The tokens table gains a SCOPE column (chip: 'fleet' / 'topology'),
and a third filter dropdown alongside state. The drawer's metadata
section shows a Scope row with a clickable jump-link back to the
MazeNET view at the right topology.
CanaryTokenRow grows a topology_id field so the drawer/list can
discriminate without re-fetching.
