Fix Docker Compose missing POSTGRES_PASSWORD

[devJaja]

Description

The root docker-compose.yml does not set POSTGRES_PASSWORD for the PostgreSQL service. PostgreSQL 16-alpine requires this or it will refuse to start.

Location

docker-compose.yml

Fix

Add POSTGRES_PASSWORD to the postgres service environment:

environment:
POSTGRES_DB: linkora
POSTGRES_PASSWORD: linkora_dev

Also add the password to the indexer and dm-relay services if they need it.

Acceptance Criteria

• PostgreSQL starts successfully with docker-compose up
• All services can connect to the database
• Password is documented in a comment as dev-only
