feat: permissions, a scoped console, and catalog management (#7)

Phase 1 of `docs/console.md` (builds on #6, whose docs commit it includes; merge #6 first).

**API**
- `permissions.ts`: `resource:action` permissions, built-in roles as bundles at a scope (hub, catalog, product), `can`/`require`, "may give" checks. A missing permission answers 403 with `missing: {permission, scope}`.
- Catalog management: settings (incl. rating ceiling, upload policy, mirroring), key rotation, operators, membership (open / approval / invite links, bans), delisting, suspension by moderators, and `GET /api/v1/catalog/changes` for catalogs.
- Membership is enforced: getting a product (403 `members_only` with the catalogs to join), the library list, and outfits relayed to others. Seeing products still needs no membership.
- Console for everyone who controls a catalog, product or hosted room; `/console/audit` (tagged entries, scoped by permission, with filters), `/console/permissions`; `/me` says whether the console is for them.
- Migration 0010: `role_assignment`, `catalog_member`, `catalog_invite`, `catalog_change`, catalog settings, audit `tags` (backfilled from old entries).

**Website**
- Console overview by what you manage; audit log page with filters; catalog list scoped to your teams; a catalog management page (settings, key, team, members, invitations, products, moderation, recent changes).
- Public catalog pages with join / ask / accept invitation / leave; product pages say "members only" and link the catalogs.

**Checked**: 43 API tests pass (8 new in `catalogs.test.ts`); API, web and db type checks; every new page rendered against a local hub for owner, operator, member, outsider and admin; the Eden DELETE-with-query calls tested against the API. Server-action forms weren't clicked through in a browser.

Not in this PR (later phases): catalog deletion requests (with cases), drafts and moderator product edits, notifications, API tokens, two-factor, imports, charts.
