[Karrp]

Description

When employee want to add some links to report 1024 characters may not be enough.
We discuss that 4096 characters should be enough.
Other option is to change type of this field from CharField to TextField and do not worry about it anymore.

Should be done:

• Change MAX_DESCRIPTION_LENGTH 1024 -> 4096

OR

• Change type of field CharField -> TextField
