Reorganize tracks

[apolignano]

This PR:

• Reorganizes tracks on the Protein summary page and hides (but makes expandable) all the ones considered "secondary". See IBU-11247 for more;
• Adds representative family track;
• Adds disordered regions track;
• Changes the residue track so that domains are not shown;
• The logic for fetching PTM data is added but currently not used given the non-completeness of the PTM data;

• Tooltip for residues now only show the position of the currently highlighted residue;
• Polar and polyelectrolytes mobidblite tracks now appear as children of the main consensus track;
• "Residues" and "other residues" tracks are now merged into one collapsible. Label links on the right only available for MemberDB residues;
• Fixed ordering logic bug that caused special tracks like alphafold confidence and pathogenic variants to not be affected by any ordering defined;
• Corrected styling following suggestions above.
