Subject: feat(api,web): budget headroom endpoint + UI chips (Phase 6)

Adds GET /api/budget returning per-provider rolling-window headroom (empty when
budget gating is unconfigured), wired from serve.go via SetBudget. The web UI
polls it and renders a chip per limited provider in the header, flagging any
under 20% remaining. New pure JS helpers formatBudgetHeadroom/
renderBudgetHeadroom are unit-tested; the endpoint is covered by Go handler
tests (empty/reports/500). UI render not browser-verified in this environment.

Completes Phase 6: spend accounting + dispatcher gating + observability surface.
