fix: #3614658 Order the header menu to the design and drop the duplicate Events link

Fixes #3614658: https://www.drupal.org/project/horizonaid/issues/3614658

Header menu did not match the design:

• Events sorted before Countries. The design orders About, Resources, Programs, Countries, Events, Donate.
• "Events" appeared twice, and the call-to-action pill read "Events" instead of "Donate". The Events view (views.view.events) shipped its own main-menu link at weight 0, duplicating the curated main--09--events.yml link. The theme renders the last main-menu item as the CTA pill, so that stray link took it.

Changes:

• Swap the two shipped menu link weights so Countries (-46) sorts before Events (-45).
• Set display.page_1.display_options.menu.type: none on views.view.events so the view stops shipping its own menu link. Donate then falls last on its own and becomes the CTA pill.

Verified in a browser on a Varbase 11 site: header renders About, Resources, Programs, Countries, Events, then Donate as the pill; Events appears once. Menu tree: Home(-50, disabled) → About(-49) → Resources(-48) → Programs(-47) → Countries(-46) → Events(-45) → Donate(0).

Note: the golden reference site still shows the old order and the duplicate link; this follows the design instead.
