fix(uat): batch — timeline overshoot, name-sync, reset-password, dashboard cleanup, queue/seed hygiene + alpha UAT findings doc

UAT findings landed across the last few Playwright + React Grab passes;
single grouped commit so the index doesn't fragment into 30 one-liners.

User & auth:
- `user-settings`: name now updates the avatar + topbar menu after save
  (was reading stale session).
- `me/password-reset`: 3 bugs (token validation, error response shape,
  redirect chain).
- Admin user permission-overrides route honours the same envelope as
  the rest of the admin surface.

Dashboard:
- Removed obsolete `revenue-breakdown-chart` + `dashboard-widgets-card`
  (replaced by the customisable widget grid).
- Strip `revenue_breakdown` from analytics route + use-analytics +
  service + integration test so nothing renders an empty card.
- Activity log timeline overshoot fix (`interest-timeline` +
  `entity-activity-feed`).
- Tightened tiles: active-deals, berth-heat-widget, pipeline-value, kpi-tile.
- `dev-mode-banner`: derive dismissed state synchronously instead of
  via an effect (set-state-in-effect lint rule).

Forms & lists (assorted polish):
- client / company / yacht / interest / reminder forms — validation +
  empty-state copy + tab transitions.
- companies/yachts list tweaks; berth recommender panel; qualification
  checklist; supplemental info request button.

Infra & misc:
- Queue workers (ai / email / notifications) — log shape +
  per-job timeout consistency.
- Auth / brochures / users schema small adjustments; seeds reflect
  permissions matrix changes.
- Scan shell + scanner manifest + AI admin page small fixes.
- `next.config.transpilePackages` adds `echarts`/`zrender`/`echarts-for-react`
  (recommended config from echarts-for-react inside Next).

Docs:
- `docs/superpowers/audits/alpha-uat-master.md` — single rolling
  cross-cutting UAT findings doc (per CLAUDE.md convention).
- `docs/BACKLOG.md`: dashboard stats cards (§I) + activity-log
  normalization (§J).
- 2026-05-18 audit log updated with this batch.
- `CLAUDE.md` — small manual UAT scaffold notes.
