Keep model-discovery errors away from picker edges (#8039)

* fix(app): pad the model picker empty state on all sides

The empty state carried vertical padding only, so the provider refresh
error it renders wrapped from edge to edge and read as attached to the
model picker's left border on web and mobile.

One padding value keeps the message off the border on every platform.

* test(app): keep model discovery errors inside picker edges

Exercise a real catalog deadline through the existing Pi RPC fixture at desktop and compact browser widths. Both gutter assertions fail without the shared padding fix.

+- Codex queries background terminals for loaded threads, including native children, and protects
+  pending provider requests. App servers without the terminal-list RPC stay resident.
+- OpenCode checks active executions and descendants. V1 checks PTYs; v2 also checks shell and
+  inbox inventories. The shared server remains leased while a session vetoes collection.
+- Pi checks streaming, compaction, pending replies, and adapter-owned operations. Known native
+  subagent signals also protect their parent through the daemon's subagent store.
+- OMP additionally requires `get_state.isSettled: true` and `hasPendingAsyncWork: false`.

+# Inline code formatting
+
+This fixture renders the production `MarkdownRenderer` with plain, bold, italic,
+combined emphasis, strikethrough and linked code, plus bold code in headings,
+lists and quotes. Toggle regular/compact text. Inline code uses the theme’s
+code-to-body size ratio at every heading level; fenced code keeps the code-size
+token. Bold and links preserve the resulting size. Check the glyphs, not the background height: native backgrounds use
+line metrics.
+
+Use a development client rebuilt from this checkout. Follow the temporary entry
+point and Metro workflow in [status-ring](../status-ring/README.md), importing
+`MarkdownFormattingRegression` from `./e2e/mobile/markdown-formatting/native`.
+Open the same Metro URL in a browser to compare web. Restore `index.ts` afterward.
+
+The package patch contains `InlineCodeFormattingTest`, which exercises actual
+Android spans in Robolectric native graphics mode, covering draw and measurement,
+span order, code inside paragraph/heading sizes, bold/italic composition, and
+links preserving code and emphasized prose fonts.
+It runs in the existing `test:android` CI job. To run only this regression locally,
+from `packages/app/android` after Expo prebuild:
+
+```sh
+./gradlew :react-native-enriched-markdown:testDebugUnitTest \
+  --tests '*InlineCodeFormattingTest' --no-daemon --max-workers=2
