refactor(brand): adopt new primitives in pages

The user-facing pages pick up the new primitives: LoginPage (21
lines) gets the new form tone + the Bill Tracker wordmark on the
auth card; TrackerPage (109 lines) gets the new cashflow timeline
geometry, the new BrandGlyph on the bucket empty state, and the
new TonedCard on the summary stack; the rest are 1-9 line
import/header adjustments. App.tsx is the lazy-loaded import for
the new brand module on the about/privacy paths.

This is commit 6 of 9 in the v0.42.0 brand refresh. Depends on
b714715 (tracker cards).
