refactor(nix): extract common system configs into reusable modules

Create 6 new NixOS modules to reduce duplication across system configs:
- hardware/wooting: Wooting keyboard udev rules and Bluetooth compat
- services/nginx-base: Common nginx server settings
- services/acme-base: ACME certificate defaults
- services/xremap: Key remapping with sensible defaults
- system/no-sleep: Disable sleep/suspend/hibernate targets
- system/kernel-tweaks: PM freeze timeout and zram configuration

Update system configuration files to use these new modules.
