This commit addresses two critical suspend/resume issues on the nb host:
1. Keyboard and touchpad not working after suspend
- Added i2c_hid_acpi kernel module
- Created systemd service to reload the module after resume
- Excluded input devices from TLP USB autosuspend
2. /nix/persist becoming read-only after suspend
- Moved swap from /nix/persist to dedicated @swap subvolume
- Added systemd service to remount /nix/persist if needed
- Separated swap from persistent data to prevent btrfs corruption
Changes:
- Created hosts/nb/modules/suspend-fixes.nix with resume hooks
- Updated swap path from /nix/persist/swapfile to /swap/swapfile
- Added /swap filesystem mount for @swap btrfs subvolume
- Added USB_EXCLUDE_INPUT=1 to TLP configuration
Note: Manual step required before deployment - create @swap subvolume.
