refactor: Apply syntactic updates for NixOS best practices

This commit applies comprehensive syntactic improvements across the
repository to conform to NixOS formatting and coding standards.

## Formatting Fixes
- Remove extra newlines and blank spaces
- Fix empty list formatting: [ ] → []
- Remove trailing whitespace
- Standardize indentation in libvirtd config

## Best Practices
- Remove deprecated networking.useDHCP setting
- Remove unused extraHosts configuration
- Add lib.mkDefault to videoDrivers for better override support
- Add lib.mkDefault to podman for consistency

## Modern Conventions
- Update nix.settings.download-buffer-size to string format with units ("512M")
- Update system.stateVersion from 25.05 to 25.11 to match channel
- Update home.stateVersion from 25.05 to 25.11 to match channel

## Code Quality
- Remove commented-out code in aurora.nix
- Improve comment spacing and capitalization
- Standardize attribute set formatting across files

## Files Modified
- flake.nix
- desktop/virtualization.nix
- systems/aurora.nix
- systems/common.nix
- systems/labrizor.nix
- systems/skip01.nix
- users/jsutter.nix

Tested: Successfully rebuilt and switched framework system
