Theme fix: Hub page CSS used non-existent variable names with dark-mode
fallbacks (--rs-surface, --rs-bg, --rs-surface-hover), so it always
rendered dark regardless of user theme. Fixed to use correct theme
variables (--rs-bg-surface, --rs-input-bg, --rs-bg-hover, etc.).
Also removed forced theme:"dark" override on the hub page route.
Subnav: Added "Create Call" to outputPaths so the module subnav shows
Create Call / Rooms / Recordings pills. Added mobile breakpoint for
the hub nav cards.
