[BOUNTY $130] Database Layer — pgAdmin4 + Redis Commander + init-databases.sh (completes #11)

[asdas6wdqc]

Summary

Completes the Database Layer Stack (Issue #11, $130 USDT) by adding pgAdmin4 (PostgreSQL admin UI), Redis Commander (Redis admin UI), and scripts/init-databases.sh — items specified in the bounty but missing from the existing 3-service implementation (PostgreSQL + Redis + MariaDB).

Changes

Services Added

Service	Image	URL	Purpose
pgAdmin 4	dpage/pgadmin4:8.11	pgadmin.${DOMAIN}	Web-based PostgreSQL administration
Redis Commander	rediscommander/redis-commander:latest	redis.${DOMAIN}	Web-based Redis administration

New Files

File	Purpose
scripts/init-databases.sh	Idempotent script to create per-service PostgreSQL databases and users
README.md	Complete guide with architecture, connection strings, Redis DB allocation

Database Layer Coverage

All 5 services now present:

Service	Status
PostgreSQL 16	existing
Redis 7	existing
MariaDB 11.4	existing
pgAdmin 4 (NEW)	added
Redis Commander (NEW)	added

Test Plan

• docker compose up -d starts all 5 services
• pgAdmin accessible at https://pgadmin.${DOMAIN}, can connect to PostgreSQL at homelab-postgres:5432
• Redis Commander accessible at https://redis.${DOMAIN}, shows Redis data
• ./scripts/init-databases.sh creates nextcloud/gitea/outline/authentik/grafana/vaultwarden/bookstack databases and users
