Annotator panel UI issues

From @strumpfe

• Control pagination size. You already have a scrollbar so giving the users the option to visualise more than 20 rows at a time should be feasible.
• lock dockbar in place
• Expand the Apollo db name (usually species name) to accommodate longer text strings. There’s room.
• Ability to hide/resize the lower panel is useful for people using smaller screens e.g. laptops.
• (To confirm) I find the Users dropdown menu useless (default is All Users) but there is no ability to select/filter for anyone who is not in the first 20 alphabetical users. This is the behavior I see in the VectorBase Apollo but have not checked others instances.
  Perhaps include other fields here e.g. status, simple QC, labels

Fixed so default 1K users.
