fix: duplicate merge button bug (#15284)

Fixes - https://github.com/twentyhq/twenty/issues/15263

- Replaced `useLoadSelectedRecordsInContextStore` with
`useLoadMergeRecords` in `useOpenMergeRecordsPageInCommandMenu` for
improved functionality.
- Updated `useMergePreview`, `useMergeRecordsActions`, and
`useMergeRecordsSettings` to utilize `mergeRecordsState` instead of the
deprecated context store hook.
- Cleaned up imports and ensured consistency across merge-related hooks.
