Pull request overview
This PR adjusts timeout and caching budgets so slow WSMAN operations are more likely to fail via the WSMAN client timeout (clean 504) rather than being cut off by the HTTP server or by duplicate concurrent authentication attempts.
Changes:
- Increase default HTTP server timeouts to allow longer-running handlers.
- Increase WSMAN connection-cache expiry to keep authenticated targets cached longer.
- Increase the “wait for auth” window to reduce concurrent handlers forking multiple WSMAN clients for the same device.

Could we make these configurable rather than hardcoded?

Will do it in a separate PR ? because these hardcoded values are spread across multiple places and need proper config wiring.

1. httpserver read/write timeout 15s to 40s so the wsman client (30s) times out first with a clean 504. 2. waitForAuth 3s to 30s so concurrent handlers share one Target instead of forking, preserving the library concurrency cap. 3. expireAfter 30s to 60s to keep the authenticated Target cached across rapid page refreshes.
