feat: add Secure Boot MOK key enrollment and module signing

Generate DKMS MOK key pair during OS install, sign all unsigned kernel
modules, and enroll the MOK certificate using the user's master password.
On reboot, MokManager prompts the user to complete enrollment. Re-enrolls
on every boot if the key exists but isn't enrolled yet. Adds setup wizard
dialog to inform the user about the MokManager prompt.
