Set real values for genericized git-config/encryption/send-alert/printing

Mirrors the azos-core change: drops the now-fully-migrated
features/{git-config,encryption,printing}, rewrites features/homey-alert
down to just the azos-homey-ntfy-alert overlay package (the ntfy-specific
remote-notification command plugged into azos.send-alert.remoteCommand),
and sets every real personal value (name/email/signing key, GPG key id,
YubiKey/browserpass/gpg-ssh toggles and keygrip/pubkey, printing username)
directly in home-manager/home.nix and nixos/configuration.nix, same place
the other personal values (azos.name, azos.headphones.devices) already
live.
