test(e2e): SSE initial-ping + heartbeat + log-frames regression guards (4 new)

Backend /agents response shape: {id, name, version, desc, enabled: bool,
running: bool, pid, instances, config_path}. parse_agents() was reading
nonexistent fields "status", "uptime_seconds", "messages_24h" so the
table showed every agent as "unknown".

Derive status from running + enabled:
  running=true                  → "running"
  running=false, enabled=false  → "disabled"
  running=false, enabled=true   → "stopped"

E2E suite now covers (13 tests, all passing in ~9s):
- connect happy + bad-host + missing-apikey + URL-trim
- shape contract (id/name/running/enabled present + bool)
- SSE smoke: /sse/status and /sse/agents/{id}/logs must NOT return
  "streaming unsupported" (depends on backend statusWriter.Flush fix
  shipped in agents_and_robots master 4822208)
- auth boundary: /health no-auth, /agents 401 sin Bearer + 401 con key falsa
- control: POST /agents/test-bot/start returns valid JSON
- detail: GET /agents/{id} returns id + logs[]
