Refactor: Allele table
In the old UI, the allele table is [placed in the sidebar](https://allel.es/docs/manual/side-bar.html) (FULL/QUICK/VISUAL), but for the refactored frontend we want to simplify with most of the allele related functionality in the sidebar (both CLASSIFICATION and REPORT) and [top allele bar](https://allel.es/docs/manual/top-bar.html) moved to a new unified table in the bottom panel.
See [wiki](https://gitlab.com/alleles/ella-frontend/-/wikis/home) for overall design. Note also that epic &16 is related, as the filtered variants are now moved to the bottom table.
