JIRA ticket: LIMS-1759

Summary:

Now that we have the Ligand, Ligand_has_PDB and BLSample_has_Ligand tables, we should have Synchweb pages to create, view, edit ligands, and add them to samples.

Changes:

• Make a copy of the View (all) Proteins page as a View (all) Ligands, with different columns
• Make a copy of the Add Protein page as an Add Ligand page, with different fields
• Make a copy of the View/Edit Protein page as a View/Edit Ligand page, with different fields, but keeping the Add PDB functionality, and also keeping the view of associated samples, containers and data collections
• Add an Add Ligand field to both the View Sample pages (there are separate ones for pucks and plates), copying the Add Component functionality

To test:

• Log into an mx proposal (eg mx23694), and select Ligands from the main menu. Click Add Ligand from the top right
• Populate the form (including testing weird characters for SMILES code) and click Add Ligand. Check you are taken to a view of the ligand.
• Add PDBs to the ligand, using Existing Code, File Upload, and Code options.
• Delete PDBs, check they stay removed after a refresh. If no other proteins or ligands use a PDB, check the PDB is deleted from the database.
• Check you can edit the other fields on the ligand
• Add a few more ligands and check the list at /ligands displays them all
• Go to a sample from a puck (eg /samples/sid/6615286), check you can add multiple ligands to it and delete them as well
• Go to a plate (eg /containers/cid/338373) and click on one of the wells. Check you can add multiple ligands to each sample in the plate (you may need to add some ligands to this proposal first), and delete them as well.
