Add Lead -> Request -> Order funnel redesign (Phase 2)

New leads entity (own numbering VTH{yy}-{seq}, 2-stage funnel, converts
into inquiries) sitting ahead of the existing Request/Order pipeline.
Request funnel expanded from 4 to 6 statuses (kp_preparation -> kp_response
-> negotiation -> signing -> converted/declined) and Order funnel from 4
to 11 (new -> ... -> completed/declined), matching the stage names/fields/
decline-reasons from the flowcharts. Decline now always requires a reason
(+ free-text detail for "other"), reused across all three entities via one
DeclineWithReason component. Added shared deal-reference fields (Incoterms,
payment terms, carrier1-3, insurance company, customs broker) to both
inquiries and orders, carried over on conversion. Added a minimal outbound
SMTP capability (reusing the existing mailbox credentials) so order
status changes can best-effort email the client, matching the stages the
diagrams call out. Per-stage informational panels (requirements + transition
criteria) shown on each entity's detail page — structure only, no SLA-timer
automation yet (explicitly deferred, per this session's scoping).

Fixed a drizzle-kit migration-generation bug by hand: the generated
INSERT...SELECT for the inquiries table rebuild referenced brand-new
columns on the pre-migration source table, which don't exist there yet.
