fix: resolve merge conflicts breaking frontend CI

- LocationsFields: remove duplicated conflict block, integrate AccessField
  into the Row-based layout (fixes JSX parse error)
- ProxyHosts/Table: migrate to updated @tanstack/react-table API (useTable,
  createColumnHelper<Features, ProxyHost>)
- Add missing Estonian translations (action.logs, column.error)
- Re-sort en.json locale keys
