feat(web): Schedule and General become ES-module pages (stage 3) (#767)

* feat(web): Schedule and General become ES-module pages (stage 3)

Schedule and General follow stage 2 (#727): no inline scripts or inline
handlers in either partial. Their code moves to static/v3/js/pages/schedule.js
and pages/general.js, started per swap-in by the page registry.

- Schedule: both pickers are drawn from the saved config carried as JSON in
  data-* attributes. The forms' hx-on save handlers become one
  htmx:afterRequest listener on the page; the forms are marked
  data-reports-result, which app.js now treats like an hx-on after-request
  handler, so a save still shows one notification.
- General: the timezone picker reads data-timezone. The Security section's
  forms and buttons are delegated data-actions; requests go through
  core/api.js, so the login redirect is quiet, and a change made just
  before a swap is still reported.
- handleScheduleResponse, handleDimScheduleResponse and webLogin stay as
  deprecated aliases through window.LEDMatrix.
- New DOM suites test_schedule_page.js and test_general_page.js; the web
  login unit suite imports the module; test_es_modules.py pins the pages,
  the aliases, and the schedule config's round trip through its attribute.

* refactor(web): no unused catch bindings or computed writes in the stage 3 modules

Codacy flagged two unused catch variables and dynamic-key writes in
pages/schedule.js and boot.js. The schedule config is read with
getAttribute, and the default days and the webLogin alias object are built
with Object.fromEntries. No behaviour change.
