common.nix now sets security.sudo.wheelNeedsPassword = true, but
--use-remote-sudo is deprecated and only prefixes commands with sudo --
it never prompts, so every remote rebuild failed. --ask-sudo-password is
the alias for --elevate=sudo --ask-elevate-password, which asks once and
feeds it via sudo --stdin.
This should have gone in with the wheelNeedsPassword change itself.

Pi's vfat partition isn't mounted at runtime (u-boot reads it pre-boot), so
/boot/firmware doesn't exist -> keyFile moved to the always-mounted root fs.
deploy flash now drops it on the ext4 root partition.
- after dd, if ~/.config/homelab/<config>/age.txt exists, mount the FAT boot
partition and drop it as sops-age.txt (mercury). Key stays off-repo + out of
the store + out of the image; no manual mount step.
