Restyle server browser UI; hide overlay on join

Restyles the server browser to match main-menu/settings (Futura PT Demibold, amber/green palette, yellow selection bars, shared panel chrome), removes SVG border strips, and tweaks modal width/layout. Adds JS + C++ coordination so the custom main-menu overlay hides when a server join begins (C++ invokes onSessionLoading and calls HideMainMenu; CompleteJoinFailure restores the menu/browser). Controller glyph tint now derives from --co-amber. Updates changelog and dev-log; includes compiled Vault109 script update.
