DMAPP-161: UI Fix for Channel Category List Items

[meKushdeepSingh]

• Updated the UI for channel category list items to visually appear as if extending off the screen.
• Refactored related code for better readability and maintainability.

[github-actions]

In the src/Globals.ts file:

1. There is a missing closing brace '}' for the AUTH_STATE object.
2. There is a missing comma ',' after the 'AUTHENTICATED' property in the AUTH_STATE object.
3. There is a missing comma ',' after the 'AuthTypeNone' property in the AUTH_TYPE object.

At the end where SCREENS and AUTH_STATE objects are defined, the 'export' keyword is missing to export these objects.

In the src/components/ui/ChannelCategories.tsx file:

1. The closing brace '}' for the functional component ChannelCategories is placed before the export statement. It should be moved after the export statement.

In the src/components/ui/ChannelsDisplayer.tsx file:

1. The useEffect hook for 'handleChannelSearch' is missing a closing curly brace '}'.
2. The closing curly brace '}' for the handleCategoryChange function should be placed after the if block, currently, it is inside the if block.
3. The 'const ChannelsDisplayer' function is missing its closing curly brace '}'.
4. The 'handleCategoryChange' function is missing a closing curly brace '}' after the setSearch(''); line.
5. The 'handleChannelSearch' function is missing a closing curly brace '}' after the setSelectedCategory(Globals.CONSTANTS.ALL_CATEGORIES); line.

All other parts of the code seem to be fine.

Please make the necessary corrections mentioned above.
