Add host agent multi-platform binary distribution and improve host details UI

Browse source 
- Build host agent binaries for all platforms (linux/darwin/windows, amd64/arm64/armv7) in Docker
- Add Makefile target for building agent binaries locally
- Add startup validation to check for missing agent binaries
- Improve download endpoint error messages with troubleshooting guidance
- Enhance host details drawer layout with better organization and visual hierarchy
- Update base images to rolling versions (node:20-alpine, golang:1.24-alpine, alpine:3.20)
