fix: clean up runtime UI and harden session expiry handling

Remove redundant "X/X LIVE" badge from runtime page, breadcrumb trail
and routes section from agent detail page (pills moved into Process
Information card). Fix session expiry: guard against concurrent 401
refresh races and skip re-entrant triggers on auth endpoints.
