refactor(ui,learn,todo,train,meditate): the navigation bar's one look, the debug section gone

The developer decided on 8 Nov 2026, after trying the variants on the
phone: the wave in the colour of the screen in view, without Material's
ripple, the indicator kept and there at once, a 1.2 s wave, top corners
of 20 dp, the bar's own neutral surface. Learn's bar stays cobalt, the
colour its tabs wash in, rather than its icon's purple.

So the bar has one look: FlushNavigationBar.waveDuration and
cornerRadius are constants, and the debug section goes from the four
Settings screens with what it switched (NavigationBarDebugSection,
debugNavigationBarStyle, effectiveNavigationBarStyle, the style record
and the variants A, C and F, the speeds, the corners and the tinted
surface). Their tests go too; those stating the look kept stay. Learn's
sign-out helper no longer has to scroll past the section.

ADR 0030's amendment of D60, the halkyon_ui README and Learn's
AGENTS.md record the decision and the alternatives set aside.

app's before a screen claims one), the destination chosen in that colour, darkened or

lightened until it reads at 4.5:1, without Material's ripple or the indicator growing,
the indicator kept, on the bar's own neutral surface. The developer chose it on 8 Nov
2026 after trying the variants live on the phone (the mockup's E): over Material's bar
alone (A), which says nothing of where a tap landed; over the wave with Material's fill
(C), whose ripple and growing indicator fight the wave; over the wave without the
indicator (F), which leaves the tab chosen marked by its colour alone; and over a
surface tinted with the screen's colour, which muddies the bar against the screen's own
wash. Learn's tabs wash in cobalt, so its bar is cobalt there, not its icon's purple,
by the developer's choice. The debug section that switched the variants went with the
decision). Driven by

workout's page opens in Home and a day's in Profile with the tabs beside them, the
route and plan editors and the recording over them; over keeping `Navigator.push`
