Apps nav + back-to-apps behavior, emoji font fallbacks, and version bump to 2.0.3

[360-Host]

Motivation

• Make it easier for users to return to the Apps launcher by standardizing back navigation across pages.
• Improve discoverability of the Apps launcher by adding an Apps entry to sidebars and topbars.
• Ensure emoji glyphs render consistently across platforms by adding emoji font-family fallbacks.
• Keep displayed project version strings consistent across files.

Description

• Replaced direct redirects like window.location.href='apps.html' with a conditional back-first pattern history.length > 1 ? history.back() : location.assign('apps.html') on many pages and added a goBackToApps() helper in a few files.
• Added Apps navigation items to multiple sidebars and topbars (for example ai.html, chat.html, news.html, search.html, games/*, zone.html, and others).
• Added emoji font-family fallbacks to UI elements that show emoji icons (for example .app-icon, .vids-nav-icon, .vids-empty-icon, .tool-btn, .vids-dropzone-icon, and .tab) to improve cross-platform emoji rendering.
• Updated visible version strings and headers across README.md, CSS/JS headers, sidebar footers and package.json to 2.0.3 (and adjusted in-page log strings where applicable).

Testing

• No automated tests were added or run as part of this change.

Keep the Apps button from leaving the site

Using history.back() here means the ← Apps control can navigate to whatever page was visited before this one (including an external site) whenever browser history exists, instead of consistently opening the Apps launcher. This is a regression from the previous direct apps.html navigation and is reproducible when arriving from search/social links; clicking ← Apps then leaves 360 rather than going to Apps.
