Replace the stale GET /api/agent/{name}/links reference with
GET /api/dashboard-state (merged in #1292). The new endpoint is
served by the agent backend and returns DashboardState carrying
links, status_text, rate_limited, ctx_tokens, and
context_window_tokens — all agent-owned fields that were previously
(mis)read by hive-c0re from disk.
Also update the ctx_tokens description: it's now sourced from
DashboardState rather than ContainerView (which no longer carries
ctx_tokens/context_window_tokens).
