Remove local cfg

[gkostin1966]

Replace local.cfg with Docker Compose environment variables
Summary
Removes backend/local.cfg and its COPY instruction from backend.dockerfile, replacing it with explicit environment: entries in the backend service of docker-compose.yml. This aligns local development with the Kubernetes ConfigMap pattern already used in production (backend-cm.jsonnet), where all DSpace configuration is delivered as P-encoded environment variables rather than baked-in config files.

Changes
backend/local.cfg — deleted; no longer needed now that its three settings are expressed as env vars in docker-compose.yml

backend.dockerfile — removed COPY ./backend/local.cfg … instruction; the root Dockerfile (used for local dev and CI) no longer copies any config file into the image

docker-compose.yml — added three env vars to the backend service:

plugin__P__sequence__P__org__P__dspace__P__authenticate__P__AuthenticationMethod=org.dspace.authenticate.PasswordAuthentication — disables OIDC, enables password auth for local dev
ip__P__bioIPsRange1=192.0.2.0/24 — non-routable placeholder so OidcAuthenticationBean does not throw NullPointerException at startup
ip__P__bioIPsRange2=192.0.2.0/24 — same
README.md — removed all backend/local.cfg references; updated "For other institutions" section and the Notes bullet to document the env-var approach instead

dspace/README.md — corrected the NOTE under "build images": replaced the stale "Kubernetes Secrets mounted directly as single files (dspace.cfg, authentication-oidc.cfg)" description with the accurate statement that production config is supplied via environment variables from a Kubernetes ConfigMap (non-sensitive) and Secrets (sensitive), both managed in deepblue-documents-kube

TODO.md / DONE.md — task tracking updated; completed tasks archived

Pull request overview

Removes the local development backend/local.cfg override file and shifts its settings into Docker Compose environment variables, aligning local configuration delivery with the production pattern of runtime configuration via env vars.

Changes:

• Deleted backend/local.cfg and removed the corresponding COPY step from backend.dockerfile.
• Added three __P__-encoded DSpace configuration environment variables to the backend service in docker-compose.yml.
• Updated documentation/task tracking to remove local.cfg references and describe the env-var approach.
