feat(supplemental-info): pre-EOI public form flow

Lets a sales rep send a client a one-shot link to fill out the
information we need before drafting the EOI (intent, dimensions,
signatory, timeline). Token-keyed: single-use, soft-expiring, scoped
to one interest + client. Public POST endpoint accepts the form
submission; CRM endpoint mints tokens for rep-initiated requests;
portal page renders the form for the recipient.

Schema: supplemental_form_tokens table (migration 0061) with port_id
+ interest_id + client_id refs, unique token, consumed_at marker.
