Add HTTP client wrapper and upgrade Axios to v1 (#594)

* refactor: add HTTP client wrapper and upgrade axios to v1

Introduce a thin HTTP wrapper (resources/scripts/http) that centralizes
axios configuration, interceptors, and auth header injection. All 43
files now import from the wrapper instead of axios directly, making
future library swaps a single-file change. Upgrade axios from 0.30.0
to 1.14.0.

* fix: restore window.Ls assignment removed during axios refactor

company.js uses window.Ls.set() to persist selected company,
which broke after the axios plugin (that set window.Ls) was deleted.
