feat(fase-1): auth, collective management, and DB migrations
- SQL migrations: users, collectives, collective_members, collective_invitations,
full RLS policies, is_active_member/is_member/is_admin helpers,
accept_invitation SECURITY DEFINER function, admin auto-promote trigger,
avatars storage bucket
- Auth refactor: replace keycloak-js with Supabase OAuth (GoTrue OIDC proxy,
Option B). signInWithOAuth({ provider: 'keycloak' }) + PKCE flow
- GoTrue config: GOTRUE_EXTERNAL_KEYCLOAK_URL + GOTRUE_EXTERNAL_KEYCLOAK_REDIRECT_URI
added to docker-compose.dev.yml; Keycloak realm updated with GoTrue callback URI
- New routes: /auth/callback, /invitation/[token], /(app)/collective/manage
- Functional onboarding: create collective or join via invite link
- Full settings page: display name (debounced), avatar (initials/emoji/upload),
language switcher, Keycloak account console link
- Components: Avatar.svelte (initials/emoji/upload with fallback),
ImageCropper.svelte (cropperjs, 1:1 crop, lazy-loaded)
- i18n: added all Fase 1 message keys (en + es); renamed 'delete' → 'action_delete'
(JS reserved word); fixed plugin-m-function-matcher major-version URL format
- Database types: manually seeded packages/types/src/database.ts from migrations
- .env.development: committed public dev defaults for SvelteKit type checking
- CLAUDE.md: documented /etc/hosts requirement for keycloak hostname
