fix(routes): restore ctx access in 15 route files broken by Phase 2.1 refactor

The modular refactor changed function signatures to destructured deps but
left internal ctx.* references intact, causing "ctx is not defined" errors
on /api/config, /api/logo, and many other endpoints. Also implements
loadTotpConfig and saveTotpConfig which were left as stubs.
