Remove "Get Involved" nav dropdown (dead links, duplicated the CTA buttons)

The "Get Involved" dropdown (Become a member / Support MSOS) had dead href="#"
links and only duplicated the two top-right buttons (Become a member, Donate).
Removed it site-wide (desktop + mobile, en/si/mk) - 390 blocks across 195 pages,
including the privacy-policy header the generators slice from, so regeneration
stays clean. Nav is now Who We Are / What We Do / For Students / News + the two
pill buttons.
