refactor(folio): delete :composeApp and retarget tooling

Removes the old monolithic module now that :core / :app:shared /
:app:ui-components / :app:androidApp own the source. Updates:

- justfile install/uninstall recipes -> :app:androidApp
- iosApp/project.yml framework path -> ../app/shared/...,
  baseName Shared (was ComposeApp); pre-build script invokes
  :app:shared:linkDebugFrameworkIosSimulatorArm64
- iosApp/iosApp/iOSApp.swift -> import Shared
- README -> mentions SQLDelight unification, drops the
  data-carrier contentDescription notes (now stale), no Layout
  section per repo convention

-- UI elements expose state via content descriptions (`account:$id:$balance`,
-  `ledger_row:$id:$signed`, `ledger_balance:$cents`, `active_account:$id`,
-  `focused_input:$field`)
+- Each screen sets a stable Compose `testTag` (`HomeScreen`, `AccountCard`,
+  `LedgerRow`, `TxnAmount`, ...). The Sanderling SDK resolves `testTag` to
+  `resource-id` on Android and `accessibilityIdentifier` on iOS.
+- Identity for list items is the visible text content (account name; txn
+  note + amount). No synthetic IDs encoded in semantics.
+- `contentDescription` is reserved for real accessibility labels, never as a
