fix: use output scale for tab bar text rendering on HiDPI displays

Browse source 
mango_tab_bar_node_update was called with a hardcoded scale of 1.0 in
both client_add_tab_bar_node and updatetitle.  On HiDPI outputs the
compositor scales the resulting 1x buffer up, producing blurry text.

Pass the client's output scale (wlr_output->scale) instead, falling
back to 1.0 when the client has no monitor assigned yet.
