feat(schema): berths.archived_at + clients.source_inquiry_id + email_bounces

Step 3 schema additions per PRE-DEPLOY-PLAN § 1.4.

berths.archived_at (+ archived_by, archive_reason) — soft-delete column
so retired moorings can be hidden from the public feed and admin lists
without losing historical interest joins. Partial index `idx_berths_active`
on (port_id) WHERE archived_at IS NULL keeps the active-only list path
fast. Already wired:
- /api/public/berths and /api/public/berths/[mooringNumber] now filter
  out archived rows.
- berths.service.listBerths defaults to active-only with an
  ?includeArchived=true escape hatch for the archive bin.

clients.source_inquiry_id — text column with ON DELETE SET NULL FK to
website_submissions(id). Preserves the linkage from a website inquiry
to the client that came out of the "Convert to client" triage flow
(P-4.5). Drives the conversion-funnel-by-source chart (Step 6). The
Drizzle column ships without `.references()` to avoid the cross-file
circular import; the FK lives in the migration SQL.

email_bounces table — bounce-monitoring storage. The DSN poller worker
(forthcoming, depends on this table existing) writes one row per parsed
bounce; consumers join via (original_send_type, original_send_id).
Three secondary indexes cover the expected access patterns (port +
recent bounces; lookup by bounced address; lookup by original send).

Schema additions plus the migration SQL are ready for `pnpm db:push`
(or the migration runner once its journal is backfilled — separate
concern, journal currently stops at 0042 despite migrations through
0065 existing on disk).
