Render the entire conversation from a template, because some parts of it must be rendered conditionally if it is a group vs private conversation. Also apply some style fixes and restore lost functionality: * Make conversation title bar fixed. * Widens message bubbles. * Unhide message list. * Restore attachment rendering. * Restore message sending and attachment file selection. * Style attachments file input as a paperclip. * Style send button like on Android and make it a submit input.
