Update all the NPM dependencies used by the Admin UI.
The dev dependencies correspond to the ones that are currently used by
an svelte app generated with the last svelte-kit version. They
deprecated some configuration options and changed some svelte
directives.
The only non-dev dependency is also updated to the last published.

Migrate the satellite admin UI web app from the Svelte template used to
generate a Svelte App scaffolding to SvelteKit.
There aren't any functional changes in the application, however, the
commit has a lot because:
1. SvelteKit uses a different directory layout and constraints to it, so
the files have been moved.
2. The files have changed its formatting due to the new default linter
configurations that SvelteKit uses.
3. The linter detected some issues with using `object` and `any` types
in Typescript, so they have been replaced by better general types
(e.g. Record).
The migration allows to use the new tooling rather than Rollup
directly, besides that will empower the future of it when it needs more
features (e.g. different routes, etc.).
