chore: unify config/ naming — test.yaml fixture + drop -dev from gateway/worker, add operator template

[chrisli30]

Summary

Makes config/ clear and internally consistent, without removing anything. Two commits:

1. Rename the test fixture to config/test.yaml

The test suite loaded its config via testutil.DefaultConfigPath, which pointed at config/gateway-dev.yaml — the same name as the gateway server config. That overloading made it unclear that running tests needs a config file at all (contributors on #620 hit testConfig is nil - gateway-dev.yaml config must be loaded with no obvious cause).

• testutil.DefaultConfigPath → test.yaml; panic messages updated.
• New config/test.example.yaml template.
• .github/scripts/generate-test-config.sh now generates config/test.yaml.
• Test files that loaded the fixture by name updated.
• README gains a "Test configuration" section.

2. Unify the local-dev config naming (drop -dev, add operator template)

The three role configs were named inconsistently — gateway-dev.yaml and worker-<chain>-dev.yaml carried a -dev suffix, but operator-<chain>.yaml did not. Now all three local-dev configs share one scheme:

gateway.yaml
worker-<chain>.yaml
operator-<chain>.yaml

(Production counterparts stay <role>[-<chain>]-railway.yaml in avs-infra.)

• Renamed gateway-dev.example.yaml → gateway.example.yaml and worker-{sepolia,base-sepolia}-dev.example.yaml → worker-*.example.yaml.
• Added config/operator-sepolia.example.yaml so all three roles have an in-repo template (operator previously had none).
• Renamed the gateway-dev make target → gateway; updated all --config paths in the Makefile, scripts, docs, and the integration test.
• Rewrote config/README.md around the uniform <role>[-<chain>].yaml scheme.

Notes

• No code behavior change — config file/target names and the test-fixture path only. go build ./... and go vet (incl. the integration tag) are clean.
• All three components' local-dev configs are preserved; nothing was deleted.

Pull request overview

This PR standardizes configuration naming under config/ by introducing a dedicated Go test fixture (config/test.yaml) and aligning local-dev role config names to a uniform <role>[-<chain>].yaml scheme (dropping -dev). It updates scripts, Make targets, CI config generation, and documentation to reflect the new naming conventions.

Changes:

• Switch the test suite’s default config fixture from config/gateway-dev.yaml to config/test.yaml, adding config/test.example.yaml and updating test references and docs.
• Rename local-dev gateway/worker config naming to drop -dev (e.g., gateway.yaml, worker-<chain>.yaml) and add an in-repo operator template (config/operator-sepolia.example.yaml).
• Update Makefile targets, helper scripts, CI setup action/script, and documentation to match the unified naming.
