Branding: Rebrand UI to 360Hub and improve file/post handling (title normalization, poster fetching)

[SasukeXDev]

Motivation

• Update the web UI from previous Surf-TG/AniHix branding to 360Hub with improved metadata and UX touches.
• Make file/post titles more consistent and safer to display by normalizing filenames and captions.
• Move poster fetching off the event loop and build post/search entries asynchronously to improve responsiveness and reliability.

Description

• Rebranded multiple server templates and fragments (home.html, index.html, dl.html, login.html, playlist.html, list.html, video.html) to use "360Hub", added meta descriptions and Open Graph tags, and tweaked navigation/hero copy and footer links.
• Updated channel and media card HTML in bot/helper/chats.py to add data attributes for platform selection, replace lazy-loading placeholder GIFs with direct poster endpoints, and add onerror fallbacks and card CSS tweaks.
• Introduced normalize_post_title in bot/helper/index.py and refactored message/file processing to use _build_post_entry with to_thread(fetch_poster) and gather to fetch posters off the event loop and apply a FALLBACK_POSTER when needed, and updated get_files to build posts from fetched history.
• Added similar asynchronous entry building in bot/helper/search.py via _build_search_entry and switched search to gather-built results, while keeping size/type/hash extraction and caching behavior intact.

Testing

• No automated test suite was present for these changes, so no unit tests were executed.
• Changes were implemented to be non-blocking and use to_thread + gather for poster fetches to avoid blocking the event loop (manual smoke checks recommended after deployment).
