Improvement: Align data tables and pagination across settings (Teams, Members, …)

[yannickmonney]

Problem

Standard data tables in the app do not share one look-and-feel, especially pagination. Teams and Members are a clear example of the same settings area feeling like two different products.

Current behaviour

• Shared primitives: DataTable, DataTablePagination, useDataTable, useListPage under app/components/ui/data-table/ and app/hooks/use-list-page.ts.
• Teams (TeamsTable + useTeamsTableConfig): useListPage search toolbar, pageSize: 20, stickyLayout: false, no page-size selector — sits in SettingsPage / SettingsSection.
• Members (MembersSettings + MemberTable): external SearchInput + client filter/sort (not useListPage); DataTable client pagination with pageSize: 10 and showPageSizeSelector: true; different column-size assumptions (≤940px / org page).
• Other settings tables (providers, API keys) follow the Teams / useListPage pattern more closely than Members.

Proposed change

• Pick one canonical settings-table pattern (prefer useListPage + DataTable as used by Teams/providers) and migrate Members and other divergent settings lists to it where client-side lists make sense.
• Unify pagination chrome: default page size, whether a page-size selector appears, footer copy, search placement (in-table vs external).
• Leave intentionally different tables alone only where the interaction model truly differs (e.g. infinite-scroll knowledge lists) — document those exceptions in the PR.

Acceptance criteria

• Teams and Members tables share the same search placement, pagination controls, and footer density.
• Other settings data tables that can share the pattern do (providers, API keys, and peers found in the sweep).
• No regression to bulk-select / row actions / sticky header behaviour already fixed for Teams (Bug: Skills settings page cannot be scrolled with the mouse wheel over the table (sticky DataTable swallows wheel events) #2381 lineage).
• Spot-check dark/light and narrow org settings width.
