fix(dashboard): ctx·Nk card badge showed 0k — use context_tokens()

/api/dashboard-state reported ctx_tokens from raw ctx_usage.input_tokens,
which is only the *uncached* input. With prompt caching the bulk of the
prompt is cache-read, so input_tokens is ~0 and every SW4RM card showed
'ctx·0k'. Use ctx_usage.context_tokens() (input + cache-read + cache-creation
= the real window size) to match the agent page (ships the full ctx_usage)
and turn.rs's cache-TTL check. Doc comment updated.
