Last slice. Promotes the Phase 3.1 in-memory AuthStore placeholder to a
Room-backed single-row auth_session table so session cookie + base URL
survive process death.
Design — hybrid storage:
- MutableStateFlow is the primary read source so interceptor-thread
reads stay synchronous (no awaiting a DAO call from inside an
OkHttp interceptor)
- Writes update the in-memory state synchronously AND launch a
write-through coroutine that persists to the DAO
- init() collects dao.observe() to keep in-memory in sync with
persisted state on app start + any external DB writes
AuthSessionDao gets partial-update queries (`setSessionCookie` /
`setBaseUrl`) so we don't have to round-trip the full row on every
mutation. First write does an upsert to seed the row.
DatabaseModule grows a @Provides for AuthSessionDao — Hilt can't inject
AppDatabase's abstract DAO accessors directly; each consumer-needed DAO
gets a thin bridge.
AuthCookieInterceptorTest updated: AuthStore now takes (dao, scope)
constructor args. Test uses mockk for the DAO and TestScope with
UnconfinedTestDispatcher so the in-memory state mutations the test
asserts on aren't affected by the asynchronous DAO writes.
