feat: add service manager script

**Motivations :**
- provide consistent lifecycle commands for the frontend and relay
- avoid port ambiguities when launching local services

**Modifications :**
- replace start-dev.sh with a start/stop/restart/status manager for ihm_client and sdk_relay
- enforce ports 3004 and 8091 with pid tracking and logging per service

**Page affectées :**
- start-dev.sh

start-dev.sh
