Add chain composition columns and function matching scores

Migrate to new MuSProt.db schema (aliased columns, new stats)

Functions: only show strings longer than 10 chars; remove chain composition from UI

Revert ranked functions to show all annotations

Ranked functions: only return GO-term annotations

Add chain_composition + binding status; refresh DB, docs, Fidelity plot

Fix score name typo: RM/RM+ -> RW/RW+ (Random-Walk potential)

Rename pair_fidelity to observation_fidelity; document feature columns

Use indexed node lookup sidecar

Make chain search use lazy node lookups

Avoid full node index load for filters
