Show pending-bias poll conflicts consistently

Meeting 13 Chrome acceptance attempted both ordinary Vote and unanimous ordinary decisions while a bias proposal was unresolved. The engine correctly returned HTTP 422, but controls merely re-enabled and no translated “resolve pending bias proposals” warning appeared. Earlier completed task tsk_bdr6nhrd5d covered content-missing for ordinary poll start; the acceptance run shows the message/flash remains unreliable across ordinary and unanimous paths. Ensure every blocked path replaces the expected controls and standard flash target in direct Turbo responses, without relying on reload. Add real response-template coverage for both actions and multiple pending bias proposals.
