Order the header menu to the design and drop the duplicate Events link

Problem/Motivation

The header menu did not match the design, in two ways.

1. The design orders the links About, Resources, Programs, Countries, Events, Donate. The shipped weights put Events before Countries.
2. "Events" appeared twice in the header, and the call-to-action pill read "Events" instead of "Donate". The Events view shipped its own main-menu link (views_view:views.events.page_1) at weight 0, duplicating the curated menu link. The theme renders the last main-menu item as the call-to-action pill (last_item_is_cta, set in the theme's menu--main.html.twig), so that stray weight-0 link took the pill.

Steps to reproduce

1. Install the Horizon Aid site template on Varbase 11 (Drupal ~11.4).
2. Load the front end and inspect the header main menu.

Observed: Events sorts before Countries, and "Events" appears twice, once as the call-to-action pill.

Proposed resolution

• Swap the two shipped menu link weights so Countries (-46) sorts before Events (-45), matching the design order About, Resources, Programs, Countries, Events, Donate.
• Turn off the Events view's own menu link (display.page_1.display_options.menu.type: none on views.view.events) so it stops duplicating the curated Events link and stops taking the call-to-action pill. Donate then falls last on its own and becomes the pill, with no special-casing.

Verified on a Varbase 11 site in a browser: the header renders About, Resources, Programs, Countries, Events, then Donate as the gold pill with the 20px radius, and Events appears once. The rendered menu tree is Home(-50, disabled) → About(-49) → Resources(-48) → Programs(-47) → Countries(-46) → Events(-45) → Donate(0).

Note for reviewers: the golden reference site still shows the older Events-before-Countries order and the same duplicate link, so this follows the design rather than that site.
