Normalize substrate naming to single NativeAppTemplate stem (#45)

Rename all `Nat`-prefixed Kotlin symbols to `NativeAppTemplate*`
(NatApp, NatAppState, NatConstants, NatPreferencesDataSource, NatNavHost,
NatAlertDialog, NatBackground, NatBottomBar, NatDispatchers,
NatNavigationBar*, NatOkHttpClient, NatPreferences, NatTheme,
NatTypography, plus rememberNatAppState) and rename the 8 corresponding
source files.

Rename Compose theme styles `Theme.Nat` and `Theme.Nat.Splash` (and the
`NightAdjusted.Theme.Nat` parent) to the `Theme.NativeAppTemplate.*`
family in themes.xml, values-night/themes.xml, and AndroidManifest.xml.

Rename the three Gradle properties `NATEMPLATE_API_{DOMAIN,PORT,SCHEME}`
to `NATIVEAPPTEMPLATE_API_*` in app/build.gradle.kts, README.md, and
CLAUDE.md.

Rename the `NATA-XXXX` error-code prefix to `NATIVEAPPTEMPLATE-XXXX`
across ApiException.kt, AppError.kt, CodedErrorTest.kt, CLAUDE.md, and
CHANGELOG.md.

Goal: every reference to the product uses one canonical stem
(`NativeAppTemplate`) so the upstream substrate renamer's
`NativeAppTemplate -> <slug-pascal>` rename pair handles every
occurrence in one rule. After this PR, `rg "Nat[A-Z]|NATEMPLATE|NATA-"`
returns zero matches outside `.git/` and `docs-private/`.
