feat: refuse to learn a first-contact key from an unpinned server

Adds an opt-in "require a pinned server" setting that gates the one
RESOLVE path that currently trusts whatever key a server hands back
for a brand-new, hand-typed address — self-certifying addresses and
already-known contacts are structurally exempt. A refusal shows an
inline recovery card in compose to fetch, compare, and pin the key
without losing the draft.

Also closes two adjacent gaps: a self-certifying address could
silently overwrite an already-trusted contact's key (now asks,
showing both fingerprints), and a contact's detail view now names its
server and pin state.
