Dokumenttikansiot asiakaskohtaisiksi

- Lisää customer_id sarake document_folders-tauluun (ALTER TABLE migraatio)
- dbLoadFolders() tukee nyt customer_id suodatusta
- dbSaveFolder() tallentaa customer_id:n kansioon
- API document_folders endpoint vastaanottaa customer_id parametrin
- JS: kansiot ladataan ja luodaan asiakaskohtaisesti (currentDocCustomerId)
- Jokaisen asiakkaan kansiorakenne on nyt itsenäinen
