feat(m1): connect & browse — first-run flow, public content, contact

Implements M1 (functional Kotlin pass, docs/android/PLAN.md §9): the
first-run base-URL connect flow, brand-seeded Material 3 theming from
/public/settings, a Retrofit/OkHttp/kotlinx-serialization client with a
runtime host-selection interceptor (the base URL is not compiled in),
the layered repository stack returning a typed ApiResult for graceful
degradation, and functional Compose screens for Home/Status, News
(+ post detail), Wiki (+ detail), CMS pages (block renderer), and the
contact form. One shared, declarative navigation drawer. No auth yet (M3).

DTOs + the Retrofit interface are hand-written and spec-aligned rather
than openapi-generated: the committed swagger-output.json is produced by
swagger-autogen and its component schemas are meta-descriptive (nested
{type, example} wrappers), not codegen-clean, so a hand-authored client
module is the pragmatic "checked-in generated module" the plan allows
(§2). Shapes were matched against the website controllers/models.

JVM unit tests cover URL normalization, host rewriting, ApiResult/UiState
mapping, and brand-color parsing. `lint test assembleDebug` green locally.
