autogen names: manage species, add species and edit prefix

[erinz2020]

1. in control panel -> fields management, change 'species management' from a modal to a page
2. on species management page, display all species names, and the prefix, count and action button
3. temporarily disable "remove a species"
4. user can add new species by clicking at "ADD SPECIES" button
5. when adding species, let user select a species and give it a codex ID prefix (must have)
6. user can edit a selected species's prefix
7. prefix can only be letters and numbers, 3-5 characters long, and must be unique.
8. the switch to turn on/off codex ID is set to checked and disabled for now.

fixes issues:

1. Autogenerate names/Codex ID - new page species management #520
2. Autogenerate names/Codex ID - New species + prefix #521
3. Autogenerate names/Codex ID - Edit species prefix #522
