fix(docker): resolve QuickStart server startup failure by fixing OIDC_CUSTOM_PARAMS YAML parse error across all 8 Compose files

[Yashsainani123]

Summary

Fixes #26775

The OpenMetadata QuickStart was broken for users running Podman and
certain Docker Compose versions. The server and execute-migrate-all
containers would crash immediately on startup while all other containers
(MySQL/PostgreSQL, Elasticsearch, Ingestion) ran fine — making the
failure very confusing to debug.

---

Root Cause

The following line existed in all 8 Docker Compose files:

OIDC_CUSTOM_PARAMS: ${OIDC_CUSTOM_PARAMS:-{}}

The {} inside the ${} variable syntax confused the Compose parser
because curly braces are special characters in Compose variable expansion.
This caused the server to receive malformed YAML:

customParams: {}}

Which crashed openmetadata.yaml parsing on startup with:
Malformed YAML at line: . . . customParams: {}}

---

Fix

Wrapped the entire value in double quotes across all 8 Docker Compose files:

OIDC_CUSTOM_PARAMS: "${OIDC_CUSTOM_PARAMS:-{}}"

This is consistent with the quoting convention already used for OIDC_SCOPE
in the same files. The fix:

• Eliminates the malformed YAML output completely
• Preserves full environment variable override capability for SSO users
• Makes the QuickStart work correctly on Podman, Docker Desktop,
  and all Compose-compatible runtimes
• Introduces zero breaking changes

---

Files Changed

8 files changed, 16 occurrences fixed (2 per file — once in
execute-migrate-all service, once in openmetadata-server service):

• docker/docker-compose-quickstart/docker-compose.yml (lines 109, 330)
• docker/docker-compose-quickstart/docker-compose-postgres.yml (lines 111, 332)
• docker/docker-compose-quickstart/docker-compose-rdf.yml (lines 151, 321)
• docker/docker-compose-openmetadata/docker-compose-openmetadata.yml (lines 63, 284)
• docker/development/docker-compose.yml (lines 118, 341)
• docker/development/docker-compose-postgres.yml (lines 121, 348)
• docker/development/docker-compose-postgres-fuseki.yml (lines 122, 353)
• docker/development/docker-compose-gcp.yml (lines 122, 336)

---

Test Plan

• All 8 files pass YAML syntax validation ✅
• Zero unquoted OIDC_CUSTOM_PARAMS:-{} lines remain in any file ✅
• Exactly 16 quoted occurrences confirmed across all 8 files ✅
• conf/openmetadata.yaml and distributed test configs untouched ✅
• git diff --name-only confirms exactly 8 files changed, nothing else ✅

---

Type of Change

• Bug fix (non-breaking — preserves all existing behavior)
