Capture phone (office) + mobile (cell) on card intake; ship v0.1.0:98

Completes business-card contact capture. The transcription prompt now labels
Phone/Mobile/Fax on separate lines, and the extractor maps an office/main number ->
phone and a cell -> mobile, never a fax. Both carry the same digit-in-source
integrity rule as email/LinkedIn: a number is kept only if its digits literally
appear in the source (or, on revise, the instruction) -- never minted. The proposal
card shows Phone + Mobile and they're editable (aliases phone/tel/office, mobile/cell).

Server: _upsert_contact_from_fundraising now accepts contact.phone + contact.mobile
and writes them to the canonical contact record (contact-level, not grid pills),
shipped in s9pk v0.1.0:98. No schema change -- the contacts columns already exist.

41/41 backend suite green + the matrix_intake units; card flow end-to-end is live-smoke.
