Fix/ Edge Browser: support textbox input when the edit invitation is not an enum

[xkopenreview]

this pr should allow a textbox in edge browser to add/edit edge

example for weight of custom max papers:

"weight": {
    "param": {
      "input": "text",
      "maximum": 100,
      "minimum": 0
    }
  }

should show a textbox for custom max papers edge

How does a default value work here? Because when I set a default value and I try to assign a reviewer that already has that number of assignments, the edge browser won't let me make the assignment, but I don't see this default value anywhere and it's not clear why I can't make the assignment.

Also, it is not very straightforward how to change this value, and changing it is not very smooth. Not sure if this will be a good experience for PCs.

please elaborate what makes you think it's not clear/smooth

• it's slow when there are a lot of edges to loads. the edge updates after the column and edges are reloaded so the page may freeze for a moment. it's worse when the custom load is two digit because it update to first the 1 digit that user input then update again to the 2 digits.
