Improved the activity type field logic and display in activity-type-field.js. Used appConfig to check the git integration flag and filtered out irrelevant or duplicate types.

To improve the activity field
The code filters out what's not real
It checks the appConfig flag
And the custom types we have
To show only the types that appeal
