refactor: releases table-related code and fix for #158 (#159)

* refactor(APIClient): updated the newly added findQuery function to use URLSearchParams instead of manually crafting the URI string itself.

* refactor: moved duplicate dashboard/release code to a separate folder: components/data-table.

* refactor(SlideOver): added proper typings to the SlideOver component and added a sanity check to prevent passing of null/undefined values to the child component before rendering.

* refactor: removed the redundant Network and Channel typings and updated relevant typings to match the backend. adapted relevant code to match these changes.

* fix(ChannelsFieldArray): fixed a bug where it was unable to add a new irc network due to the validation object being initialized as non-empty (formik requires that successful validated entries return empty objects)

* refactor(screens/settings/Irc): replaced incorrect typings, sanitized potentially null values and cleaned up the code.

* fix: included changes should fix issue #158 as well.

* feat: send chan empty array
