Optimize deployment size: 73MB -> 49MB (32.8% reduction)

- Enable IL trimming and compression in Client project
- Remove source maps from production builds (saved ~6 MB)
- Remove unused Radzen CSS themes - keep only standard-base.css (saved ~14 MB)
- Disable debug symbols in Release builds (saved ~4 MB)
- Total savings: 24 MB

This should significantly speed up F1 tier deployments by reducing:
- Zip extraction time
- File I/O operations
- Network transfer time
