## Summary
* Fixes extreme slowness (browser-crashing on filter) on
`/org/[slug]/team` for orgs with 200+ members.
* Root cause: `MemberRow`/`MemberActions` each independently subscribed
to org-wide React Query data (roles, projects, permissions, feature
flags) and rendered a hidden `UpdateRolesPanel` per row. Filtering
caused hundreds of duplicate query observers to mount/unmount on every
keystroke, each scheduling its own stale-timeout bookkeeping and
blocking the main thread for multiple seconds.
* Hoisted all org-wide data fetching (`useOrganizationRolesV2Query`,
`useOrgProjectsInfiniteQuery`, `usePermissionsQuery`,
`useSelectedOrganizationQuery`, `useIsFeatureEnabled`) to `MembersView`
and passed the results down as props.
* Replaced the per-row `useAsyncCheckPermissions` hook calls in
`MemberActions` with the underlying pure `doPermissionsCheck` function
memoized locally, removing their internal query subscriptions.
* Simplified `useGetRolesManagementPermissions` to stop calling a
query-fetching fallback hook that was unreachable given all current call
sites already pass `permissions`/`orgSlug` directly.
* Replaced 200 hidden per-row `UpdateRolesPanel` instances with a single
shared instance owned by `MembersView`, opened via an `onManageAccess`
callback.
* Cached the regex built by `doPermissionsCheck`'s `toRegexpString`
instead of rebuilding it on every permission check.
Diagnosed from two Chrome performance traces of the team page while
typing in the filter box (multi-second main-thread blocking tasks traced
to React Query `QueryObserver` mount/unmount storms).
## Test plan
- [X] `tsc --noEmit` clean (only one pre-existing, unrelated error in
`packages/ui-patterns`)
- [X] `eslint` clean on all changed files (only pre-existing warnings)
- [X] `vitest run tests/components/Organization/TeamSettings` — 51 tests
pass
- [X] Manually verify filtering is smooth on an org with 200+ members

## Summary by CodeRabbit
* **New Features**
* Team Settings provides centralized member access and role management.
* Members can update roles through the access-management panel.
* **Improvements**
* Permission checks now more accurately handle organization and project
scopes, including wildcard patterns.
* Member search is debounced for smoother filtering while typing.
* Access-management actions use current organization members, roles,
permissions, and feature settings.
