feat(submissions): Implement submissions page with paginated table

This commit introduces a new page for users to view their submissions in a structured and paginated table. This allows users to easily track their submission history and access key details.

The main changes include:
- A new page at `/submissions` to display the submissions list.
- A `SubmissionsTable` component to render submission data, including title, country, status, and a link to the submission URL.
- Integration of `react-paginate` to handle navigation through large sets of data.
- A new `useSubmissions` custom hook using TanStack Query for efficient, paginated data fetching from the API.
- Addition of the `currency-symbol-map` dependency to display prices with the correct currency symbol.
