refactor: refactor date handling across components to use date-fns and Intl.DateTimeFormat

- Replaced moment.js usage with Intl.DateTimeFormat for date formatting in various components.
- Introduced utility functions `normalizeDateLocale` and `formatWithIntl` for locale normalization and date formatting.
- Updated PlaylistSwitcher, RecentPlaylists, ContentCard, EPG components, and MultiEpgContainer to utilize the new date formatting approach.
- Removed moment-date pipe and related tests, simplifying date handling logic.
- Ensured all date displays respect the current locale settings.
