chore: scrub "Lamassu" from shipped labels

The kiosk's <title> still read "Lamassu ATM" — visible as the browser tab
on the public demo, and inherited by the Electron window. The product has
been bitSpire since the rename; Lamassu belongs in the provenance credits
(README, the c0b69d1 boundary note), not on the artifact.

Rename the user-facing labels that ship: the page title, the flake
description (surfaces in `nix flake metadata`), the ISO build banner, the
header comments on the live-USB config / udev rules / app derivation that
land on the machine image, and the workspace packages' descriptions.

Deliberately NOT touched, because they are identifiers rather than labels
and renaming them has deployed-machine consequences:
- VITE_LAMASSU_MACHINE_MODEL / VITE_LAMASSU_FIAT_CODE (provisioned .env)
- LamassuEventKind (exported enum)
- localStorage keys lamassu-theme / lamassu-color-mode (would reset
  every machine's stored theme)
- docker container names + devenv scripts (dev-only)
- the packages/hal Cargo crate name
Hardware names in HAL driver comments ("Lamassu Sintra", "Douro", "Tejo")
stay: those are the physical machines' real names — that IS the credit.
