Follow-up to #8650. This addresses the items from the [second-pass
review](https://github.com/block/buzz/pull/8650#pullrequestreview-5700660448),
which arrived after #8650 merged.
- **Setting menu semantics.** Options in the shared `BuzzSettingMenu`
(model, reasoning effort, and channel TTL) expose their checked state
again. The trigger is announced as a button with enabled and expanded
state, so a disabled "Reasoning effort" no longer reads as plain text.
The `PopupMenuButton` this menu replaced also provided a named route and
a "Dismiss menu" action. `MenuAnchor` does not provide them, so this PR
does not restore them.
- **Remote listing failures.** "Could not load agents" for a failed
Builderlab listing now appears only in communities that support remote
agents. For example, it no longer appears in a non-hosted community
while signed in.
- **Add agent during a community reload.** No change needed here. #8693
already disables Add while the page has no community.
### Validation
- Added tests: setting-menu checked, button, enabled and expanded
semantics; a failed remote listing stays hidden where remote agents are
off. Both fail without these changes.
- Mobile analysis is clean, and the Agents and shared widget tests pass
locally after rebasing onto #8693.
- Not covered: VoiceOver on a device.

Follow-up to [#8626](https://github.com/block/buzz/pull/8626). Mobile
remote-agent creation now matches desktop.
- **Model and reasoning effort:** Create agent has Model and Reasoning
effort menus. Their options come from the remote service's catalog, and
nothing is preselected (same as desktop). The server checks the
selection against the catalog again before registering, and saves it on
the agent.
- **Builderlab gate:** creating a remote agent requires a hosted
community and Builderlab sign-in. The Agents directory, community bots
and the Bestie chooser stay available without it. Signing out closes an
open Create agent sheet; the Agents sheet stays open.
- **Enrollment:** `attest-agent` enrolls the agent in the requested
community, as on desktop, so the separate `add-buzz-subscription` call
is gone.
- **Quieter progress:** spinners replace the progress bars and the
"Working…" label. Status and success text ("is ready", "Remote agent
deleted.", setup steps) is gone, and only failures show text. Refreshing
an already-loaded agent list no longer blanks it.
- **Shared setting menu:** `BuzzSettingMenu` is a bordered setting row
that opens a Material 3 menu spanning the row's width. Opening it
dismisses the keyboard. The channel-TTL setting in Create channel uses
it too.
Agent avatars and QR/link-based creation follow in stacked PRs. Editing
existing agents comes later.

### Validation
- Checked on the staging iOS simulator with a Builderlab account: the
Agents list, the Create sheet, and the model and effort menus (including
with the keyboard open).
- Added tests: catalog-gated model selection (including switching models
clears an unsupported effort), the Builderlab sign-in gate, controller
creation and resume with a model, a failed listing reported instead of
an empty registry, and create sheet busy and failure states (including
the catalog reload after a rejected create).
- The hosted-only agent tests are skipped without Builderlab defines,
which `mobile-test` doesn't pass. They pass locally with the staging
defines (20/20).
- Not covered: Android.
