Add brewing section, plan chat, roaster learning, API tokens, Swagger docs, and full backup

Brewing:
- roasted_beans + brews tables; /beans (bean management with LLM URL
  prefill) and /brews (silhouette brewer picker across immersion/
  percolation/espresso, recipe fields, auto ratio, 0-10 rating, tasting
  notes); bean remaining weight derived from logged brew doses
- Green inventory lot form also prefills from a product URL

Navigation/UX:
- Side nav is now generated from one definition in nav.js, grouped
  Roasting / Brewing / account, consistent on every page

LLM:
- 'Ask the LLM' chat drawer on the planner (stateless /api/plan-chat)
  grounded in the plan, computed ledger, learned pace, and a new
  roaster-behavior profile aggregated from uploaded .alogs
  (/api/roaster-profile: TP lag, phase RoR, median milestone temps)
- The profile also feeds roast reviews and the planner curve's fallback
  milestone temps

API platform:
- User-generated bearer tokens (rpt_…) with account-page management;
  token requests skip CSRF; hand-authored OpenAPI 3 spec at
  /api/openapi.json rendered by self-hosted Swagger UI at /api-docs
- Full-database backup export/import (admin) + per-user data export
