Korrespond: add Refine pass with jurisdiction-scoped formal citations

After the first draft is rendered, a "Refine with citations" panel offers a
3rd-pass rewrite scoped to the user's choice of Norwegian law, ECHR (EMK +
HUDOC case law), or both. Refine pulls fresh corpus chunks limited to the
chosen jurisdiction's slices, rewrites inline cites in formal style ("jf.
forvaltningsloven § 17", "jf. Strand Lobben m.fl. mot Norge, EMD-37283/13,
§§ 207–214"), and appends a Rettskilder block listing every authority.
Hard-RAG grounding carries through — refine cannot cite anything that
wasn't retrieved. Costs 1 additional credit; the original draft stays in
place and the refined version appears below it.
