Improve type safety and remove unnecessary store operations (#18622)

## Summary
This PR improves type safety across the codebase by replacing generic
`any` types with proper TypeScript types, removes unnecessary record
store operations, and adds TODO comments for future refactoring of
useEffect hooks.

## Key Changes

### Type Safety Improvements
- **SettingsAgentTurnDetail.tsx**: Replaced `any` type annotations with
proper `AgentMessage` type from generated GraphQL types
- **useCreateManyRecords.ts**: Added `RecordGqlNode` type for better
type safety when handling mutation responses
- **useLazyFindOneRecord.ts**: Replaced generic `Record<string, any>`
with `Record<string, RecordGqlNode>` for improved type checking

### Removed Unnecessary Operations
- **EventCardCalendarEvent.tsx**: Removed unused
`useUpsertRecordsInStore` hook and its associated useEffect that was
upserting calendar event records to the store
- **EventCardMessage.tsx**: Removed unused `useUpsertRecordsInStore`
hook and its associated useEffect that was upserting message records to
the store

### Conditional Query Execution
- **useLoadCurrentUser.ts**: Made the `FindAllCoreViewsDocument` query
conditional - only executes when `isOnAWorkspace` is true, preventing
unnecessary queries for users not on a workspace

### Documentation
- Added TODO comments in multiple files (`useAgentChatData.ts`,
`useWorkspaceFromInviteHash.ts`, `useGetPublicWorkspaceDataByDomain.ts`,
`useFindManyRecords.ts`, `useSingleRecordPickerPerformSearch.ts`)
referencing PR #18584 for future refactoring of useEffect hooks to avoid
unnecessary re-renders

## Implementation Details
- The removal of store upsert operations suggests these records are
already being managed elsewhere or the operations were redundant
- Type improvements maintain backward compatibility while providing
better IDE support and compile-time checking
- Conditional query execution reduces unnecessary network requests and
improves performance for non-workspace users
