fix(console): fix sidebar active route highlight matching and apply primary color hover styling

- Normalize route matching with cleanPath and cleanHref prefix comparison
- Highlight all sub-routes (Research Projects, Research Areas, Members, etc.) correctly when active
- Replace white hover effect with primary cobalt hover color (hover:bg-cobalt/10 hover:text-cobalt)
- Verified with E2E test suite (Exit Code 0)
