Build the Platform Core, Chat, and member integrations UI - #9687

…er grew, instead of re-recording every row

… blocks on the shared settings parts

API keys: one Manage section holds New API key and the personal-keys SwitchRow, each list is a
SettingsList, the read is SettingsRead, and Copy name is gone. BYOK opens a provider's keys as a
sub-view through useSettingsSubview, with the key form's draft inside its dialog. Custom tools and
custom blocks open their create flow through useSettingsSubview, end their list with a New row,
commit edits through SettingsSaveBar and delete from a Manage section. The custom block editor
splits into Source, Inputs and Outputs and no longer sets state during render.

The sync detail commits mapping edits through SettingsSaveBar, the fork and activity sub-views open
through useSettingsSubview, Forks and Events are SettingsLists, the synced-workflow tree opens
collapsed, and undoing a sync reads Undo last sync from button to confirm.

…ention, data drains, audit logs and access control

The task list pages through the inbox's cursor with the shared load-more and no longer echoes the
search; the address is one row with Change address; members collapse into one summary row; each
dialog holds its own draft; the enable switch is a SwitchRow; and the disable confirm says what
actually happens: the address is deleted, and turning the inbox back on makes a new one.

…red switch rows, and Knowledge graphs as a form dialog

The route picks the live or session profile, theme row and cookie choices, so
the views stay prop-driven. Profile accepts the picture types it validates.
Account loses the Home page row and its duplicate anonymous guard. Privacy keeps
its sub-view, since hosted adds the cookie choices; its rows are SwitchRows and
the cookie note is Muted. The consent banner's switches are SwitchRows.
Knowledge graphs reads its name from a form Modal, which owns pending, and its
section no longer repeats the page title.

The page reads the request's user agent on the server, so macOS shows ⌘⇧P and
others Ctrl+Shift+P, with no hydration flip. Shortcut rows keep no description
by design: the label names the action and the keys are its value. The DOM test
restated the list and the hard-coded key strings; the Record over CommandId
already fails type-check for an unlisted command.

…and one theme vocabulary

Desktop: every toggle through useDesktopPreferenceMutation and SwitchRow, the
device read folded into the page's one read, Computer use below the device
settings with its running action still on top, Allowed as a StatusTag, approved
apps as a query, and a menu-bar row that says what it does.
Browser: one Clear browsing data row whose dialog says what it clears, saved
passwords read only on the Passwords view through a query, the open password in
the URL, Delete for every removal, and confirms that fail in their dialog
instead of reading a missing bridge as success.
Terminal: its section named for the page's one job, SwitchRow, Preferences in
the TSDoc. Browser, Terminal and the terminal panel share Match Sim, Light and
Dark. Drops the migrated pages' allowlist entries.

… settings parts

The MCP list reads each server's stored tool count instead of discovering every server's tools, and
opening a server, by a click or a shared link, re-discovers that server alone through a probe query
its detail mounts, which replaces the ref-guarded deep-link effect. Both MCP pages open servers
through useSettingsSubview, list them in a SettingsList that ends in a New row, delete from a
Manage section, and drop counts from headings and the repeated server name. Deployed workflows load
only while the create dialog is open.

…ed on the shared settings parts

The sandbox editor owns its draft and mutations, keyed by the sandbox it opened, which retires the
draft-owner state set during render and the eighteen drilled props; create opens through
useSettingsSubview and submits through Create sandbox, edits through SettingsSaveBar. Teammates
lists members and invites under one SettingsList ending in Invite teammates, whose button is
disabled with its reason, or reads View plans where a plan limit closes it. Recently deleted merges
restored rows without splicing during render and labels types in sentence case.

…arts

Members: SectionStack and SettingsList in place of a local panel and EmptyState
inside a surface, no counts in headings, Invite's disabledReason, confirm titles
that name the object.

Billing and Insights share one PeriodPicker (no getElementById focus hack) and one
UsageLedger with Export in its header; the export busy flag resets in finally.
Credit usage is gated on the server instead of an effect redirect. Invoices are a
ResourceList of ActivityRows; Manage in Stripe is the one portal action. On-demand
uses SwitchRow with the lock reason in its description.

Insights: the heatmap fits the column without a ScrollArea (narrow widths drop the
oldest weeks through a container query), one UsageBlock replaces three hand-built
sections, the toolbar is SectionToolbar, Activity's workspace drill-in uses
DetailHeader, and the activity summary lives on Activity only.

… pager

People pages in the browser through an infinite query seeded by the server read,
ending in LoadMoreFooter, in place of a client slice plus a server Next page; the
view no longer filters what the read already matched. Removing a workspace's
access is a row menu Remove behind ConfirmDialog, and its 1000-workspace limit is
a model constant. The provider icon mapping moves into the model, the tab strip
is no longer wrapped in an ActionRow, and the lists drop the headings that
repeated their tab. Searches carry placeholders and show only with rows to
search; empty lists are EmptyStates outside the surface with their create action.

… the shared parts

Whitelabeling commits through SettingsSaveBar, which now owns its leave guard.
Recently deleted: Restoring…, a placeholder with …, no search with nothing
deleted, SectionStack. Requests: SwitchRow for Allow requests, one toolbar of
search and status filter by the list, a plain Requests heading. Links: one
SectionToolbar (bordered search, Sort, New link), no second New link in the empty
state, the table's default viewport offset instead of hand arithmetic, and the
name cell and row menu split into their own files. Drops the migrated pages'
allowlist entries.

The secrets editor splits into GenericSecrets, WorkspaceSecrets, SecretRows and the row cells, commits
through SettingsSaveBar, and shows an empty scope as a SettingsList empty state with Add secret
instead of a blank row under a disabled Save. A secret's detail and its usage view open through
useSettingsSubview (?secret=, ?secret-view=), so the secrets section no longer declares a path
subpath; the detail drops the repeated Key field, its visibility switch is a SwitchRow, and the
credential form leaves the leave guard to the save bar.
