fix: resolve frontend routing, API mismatches, and missing UI components

- Add servers list page and missing routes (servers, settings redirect, account security)
- Fix members page .map error (API returns { data } wrapper, not flat array)
- Fix auth store fetchUser expecting flat User but API returns { user } wrapper
- Add node token display dialog after creation
- Add allocation management UI to node detail page
- Add account security page with password change
- Add change-password API endpoint
- Add node servers and stats API endpoints
- Fix config save using PATCH instead of PUT, add api.put method
- Fix audit logs field name mismatch (userName vs username)
- Replace admin nodes page to avoid orgId dependency
- Remove duplicate sidebar nav items
