refactor: use Laravel route() helper for shared variable URLs

- Replace hardcoded URL paths in getScopeUrl() with Laravel's route() helper
- Add scopeUrls property to EnvVarInput component with named routes
- Pass projectUuid and environmentUuid to enable context-specific environment links
- Environment scope link now navigates to the specific project/environment shared variables page
