fix: increase curl timeout to 600s for long-running AI tasks

CURLOPT_TIMEOUT was 180s. Generating a consultation summary requires
up to 10 AI iterations at ~20s each, regularly hitting the limit and
causing a "שגיאה בתקשורת" error in the UI before Shira could respond.

Raised to 600s. The shira-hermes agent runner now also enforces a 570s
total budget so it returns a clean Hebrew message if the limit is hit,
rather than the PHP connection being cut mid-response.
