refactor(sales): consolidate pipeline stages + wire EOI auto-advance

The 8→9 stage refresh from earlier today only updated constants.ts and the DB —
20 component/service files still hardcoded the old enum, leaving labels blank,
filter dropdowns wrong, kanban columns mismatched, and the analytics funnel
silently dropping new-stage rows. The platform also never advanced
pipelineStage on EOI lifecycle events: documents.service.ts wrote eoiStatus
but left the user-visible stage stuck.

This commit closes both gaps:

  1. Single source of truth in src/lib/constants.ts — adds STAGE_LABELS,
     STAGE_BADGE, STAGE_DOT, STAGE_WEIGHTS, STAGE_TRANSITIONS plus
     stageLabel / stageBadgeClass / stageDotClass / safeStage /
     canTransitionStage helpers. components/clients/pipeline-constants.ts
     becomes a re-export shim so existing imports keep working.

  2. 18 stale-enum surfaces migrated — interest list (table, card, filters,
     form, stage picker), pipeline board, client card, berth interests tab,
     portal client interests page, dashboard pipeline / funnel / revenue-
     forecast charts, settings pipeline_weights default, dashboard.service
     weights, analytics.service funnel stages, alert-rules stale-interest
     filter, interest-scoring stage rank.

  3. Documents tab wired into interest detail — replaced the placeholder in
     interest-tabs.tsx with InterestDocumentsTab + InterestFilesTab so the
     EOI launcher is back where salespeople work.

  4. Auto-advance — new advanceStageIfBehind() in interests.service.ts
     (forward-only, no-op if interest is already past the target). Called
     from documents.service.ts on send (→ eoi_sent), Documenso completed
     webhook (→ eoi_signed), and manual signed-EOI upload (→ eoi_signed).

  5. Transition guard — canTransitionStage() blocks egregious skips
     (e.g. completed → open, open → contract_signed). Enforced in
     changeInterestStage before the DB write.

Tests updated to reflect the 9-stage model. tsc clean, vitest 832/832,
ESLint clean on every file touched.
