fix(web): improve context menu positioning and forward UX

- render chat/message context menus via portal to document.body

- clamp menu coordinates to viewport while keeping near-cursor placement

- remove visible chat id fallbacks from chat/discover UI

- hide 'delete for everyone' checkbox for channels; show channel-specific hint

- replace forward-by-chat-id prompt with searchable chat picker modal
