fix(web,mobile): subagent cards show which account each subagent runs on#24898

Pass the card surface to ProviderInstanceIcon.

ProviderInstanceIcon uses border-screen when surfaceColor is omitted. This badge is positioned over a bg-card wrapper, so its border can use the screen color instead of the card color. Pass --color-card as surfaceColor.

Pass the settings-derived registry agent ID to the mobile subagent badge check.

SubagentAvatar builds provider records without acpRegistryAgentId. shouldShowInstanceBadge compares that field for ACP registry entries. When two ACP registry instances share a driver, have no valid accent, and have distinct agent IDs in settings, both records have undefined IDs. The helper treats them as one identity and returns true. The badge then appears even though the helper's own contract hides it for distinct ACP agents.

The mobile thread handoff row already derives this ID from config.settings.providerInstances. The subagent avatar should use the same derivation. Instances with no available agent ID still have undefined and keep the current badge behavior.

Pass providerInstances={config?.settings.providerInstances ?? {}} where SubagentAvatar is rendered. ThreadSubagentGroup already reads config.

Apply settings-aware provider branding before the badge check.

EnvironmentSubagentAvatar passes unbranded entries to shouldShowInstanceBadge(). deriveProviderInstanceEntries() leaves acpRegistryAgentId unset, so two distinct ACP agents with the same driver and no accent can be counted as one identity and receive an instance badge.

Use applyProviderInstanceSettings() with the environment settings before evaluating the badge. This web correction is separate from the mobile provider mapping.

Pass the branded ACP icon and agent ID to the subagent avatar.

EnvironmentSubagentAvatar applies settings branding to the display name, accent color, and badge, but it reads iconUrl from the unbranded provider snapshot. For ACP instances with explicit settings, the configured registryIconUrl and agentId never reach ProviderInstanceIcon. Select the branded entry's acpRegistryIconUrl and acpRegistryAgentId instead:

Suggested fix

diff

1	- const iconUrl = useAtomValue(
2	- providersAtom,
3	- (providers) =>
4	- providers?.find((provider) => provider.instanceId === providerInstanceId)?.iconUrl,
5	- );
6	+ const iconUrl = useAtomValue(
7	+ providersAtom,
8	+ (providers) =>
9	+ entries(providers).find((entry) => entry.instanceId === providerInstanceId)
10	+ ?.acpRegistryIconUrl,
11	+ );
12	+ const acpRegistryAgentId = useAtomValue(
13	+ providersAtom,
14	+ (providers) =>
15	+ entries(providers).find((entry) => entry.instanceId === providerInstanceId)
16	+ ?.acpRegistryAgentId,
17	+ );
18	return (
19	<SubagentAvatar
20	{...props}
21	displayName={displayName}
22	iconUrl={iconUrl}
23	+ acpRegistryAgentId={acpRegistryAgentId}
24	accentColor={accentColor}
25	showBadge={showBadge}
26	/>

SubagentAvatar must also accept acpRegistryAgentId and forward it to ProviderInstanceIcon as acpRegistryAgentId. Its props declaration was not inspected, so that change is not shown.
