swarm UI: fetch linked accounts only for the opened agent

The detail panel makes one request for the agent it shows,
GET /api/hives/{hive}/agents/{agent}/linked-accounts, which returns every
matrix, forge and github account of that agent as names and hosts. The
all-agents route and the table's matrix-column rows are removed, so the
table makes no linked-accounts request. The panel stays keyed by
hive/agent. The bao grant is unchanged.
