Remove placeholder buttons (Threads, Inbox, Help) from channel and DM headers. Add full-text message search with backend endpoints for both space channels and DMs, supporting filters (from, has, before, after) and pagination. Search popover with debounced input, highlighted matches, and jump-to-message that scrolls with a highlight animation. Includes messages/around endpoints for loading context when jumping to uncached messages.
