PHASE 1 of the UI redesign. Adds semantic colour roles that keep brand gold out
of health states, layout and typography aliases so views stop hand-rolling
padding, and the reusable widgets the redesign depends on: PlanBadge, QuotaBar,
QuotaBucketWidget (stable key plus in-place update), SearchField, FilterButton,
ActionButton, IconButton, EmptyState, RouteTargetWidget, AccountCardWidget,
AgentCardWidget, ConfirmDialog, Toast, plus ellipsize/tooltip helpers for long
account identities.
test_unknown_quota_is_supported_explicitly compared inspect's resolved
annotation object against source strings, so it could only pass while being
skipped; components.py has no `from __future__ import annotations`. Rewritten
to assert through typing.get_args that QuotaBar.set_value accepts None.
