Fix Foundry UI bugs: org names, hanging sessions, and wrong repo creation

- Fix org display name using GitHub description instead of name field
- Fix createWorkbenchSession hanging when sandbox is provisioning
- Fix auto-session creation retry storm on errors
- Fix task creation using wrong repo due to React state race conditions
- Remove Bun hot-reload from backend Dockerfile (causes port drift)
- Add GitHub sync/install status to dev panel
