- Rewrite template to flat KEY=VALUE (DATABASE_URL, LISTEN_ADDR,
BASE_URL, etc.) -- the TOML-style sections Miniflux would ignore
- Hardcode deploy-time infra constants (LISTEN_ADDR, sslmode, db host,
RUN_MIGRATIONS, CREATE_ADMIN) directly in the template literal
- Drop the 7 MINIFLUX_* defaults from .env.sample (they were
hardcoded non-user-tunable values shoehorned into the env file)
- Remove now-redundant RUN_MIGRATIONS env var from compose.yml
- Add missing MINIFLUX_* env vars referenced by config.yml.tmpl
- Tell miniflux to actually load the config file via -c flag
- Remove redundant env-var injection that shadowed config values
- Fix invalid single-quoted Go template literal in postgres healthcheck
