taylanbakircioglu 30a4424f61 fix: Use temp file for heartbeat to avoid argument list too long error ...

PRODUCTION BUG: Argument list too long when sending large stats CSV

ERROR MESSAGE:
"Heartbeat failed (HTTP /usr/local/bin/haproxy-agent: line 417: /usr/bin/curl: Argument list too long)"

ROOT CAUSE:
- curl output capture exceeded system argument list limit
- Large stats CSV (>200KB, production can be >1MB)
- Shell variable assignment hit system limits

SOLUTION:
- Redirect curl output to temp file (/tmp/heartbeat_response_$$.txt)
- Read HTTP code and response body from temp file
- Cleanup temp file immediately after use

BENEFITS:
- No size limit on HTTP responses
- Production-safe for large HAProxy instances
- Better error handling with detailed logging

FILES CHANGED:
- backend/utils/agent_scripts/linux_install.sh
- backend/utils/agent_scripts/macos_install.sh
- Updated both embedded daemon and installer functions
