ALL-1874 PR-3: Frontend — ResolutionRules tab in DataReviewPage (list + workspace config)

## Context Linear issue ALL-1874. First frontend PR. Can be developed in parallel with PR-2 (testRule) since it only consumes the already-existing queries: `resolutionRules`, `workspaceResolutionConfig`, `updateResolutionRule` (enable/disable toggle), `updateWorkspaceResolutionConfig`. ## Key files - `apps/dashboard/components/pages/DataReviewPage.tsx` — add "rules" tab to TABS array and DataReviewTab union type - `apps/dashboard/components/pages/DataReviewPage/` — create new RulesTab.tsx here (same pattern as AutoFixedTab.tsx, ReviewLogTab.tsx) - Existing GraphQL fragments/hooks: check `apps/dashboard/graphql/` or `apps/dashboard/hooks/` for any existing resolutionRules hook; if none exists, create `apps/dashboard/hooks/useResolutionRules.ts` - `apps/dashboard/graphql/identity/` — add resolutionRules.gql and workspaceResolutionConfig.gql query files if not present; check codegen output ## UI spec (Rule List tab) ### RulesTab: top section = WorkspaceConfig toggles - Toggle for `ruleAutoApply` on/off (label: "Auto-apply rules") - Show `aiThreshold` as read-only info (editing aiThreshold is out of scope for this PR) - Call `updateWorkspaceResolutionConfig` mutation on toggle ### RulesTab: bottom section = Rule list table - Use existing `DataTable` component pattern (same as other tabs) - Columns: Name, Issue Type, Field, Matcher (summary), Transform (summary), Priority, Enabled toggle, Actions (Edit | Delete) - For platform-default rules (workspaceId==null): show badge "Platform default"; disable Delete button; Edit disabled (non super-admin) - Enabled toggle calls `updateResolutionRule({ id, enabled })` inline - Reorder: show priority as editable inline number input (no drag-and-drop in this PR — that is a follow-up) - Add rule button opens the RuleEditorModal (stub in this PR — clicking "Add rule" can show a toast "Coming soon" or open an empty modal shell; full editor is PR-4) - Delete calls `deleteResolutionRule` with a confirm dialog ## Acceptance test - RulesTab renders in a Storybook story or snapshot test with mocked data (3 workspace rules + 1 platform default) - Enable/disable toggle fires updateResolutionRule mutation - ruleAutoApply toggle fires updateWorkspaceResolutionConfig mutation - Platform-default rule shows badge and delete button is disabled ## Notes - Do NOT implement the editor form in this PR — that is PR-4 - DataReviewPage.tsx tabs: change `type DataReviewTab = "queue" | "review-log" | "auto-fixed" | "change-log"` to add `| "rules"` - Add `{ id: "rules", label: "Rules" }` to the TABS array - No new backend work needed — all GraphQL operations already exist from prior PRs
