bibliography: fix commands, add manual entry, universal search

- biblio-crossref-lookup doesn't exist; use biblio-lookup (universal)
- biblio-doi: require biblio before biblio-doi (load order fix)
- my/bib-insert-manual: template for 8 entry types with cursor at KEY
- All commands lazy-load biblio via (require 'biblio)
- SPC B s = universal search (prompts for backend: CrossRef/arXiv/DBLP)
- SPC B m = manual entry template
- SPC B D = import by DOI
