Fix/dev hints (#304)

* chore: remove unused axios dep; replace npm run with node --run

axios was listed as a direct UI dependency but had no import sites.
Switch MagicMirror start command and CI lint step from `npm run` to
`node --run` (available in Node 22+, matches the current test matrix).

* fix: replace git checkout . with git restore . for working tree reset

git restore is the correct modern replacement for discarding working
tree changes; git switch is for branch switching.
