feat(export-file-txt): migrate connector to manager-supported mode (#7222)

[Helene Nguyen (helene-nguyen)]

Proposed changes

• Migrate internal-export-file/export-file-txt to manager-supported mode: replace the config.yml / os.environ loading with a Pydantic ConnectorSettings built on connectors-sdk (BaseConnectorSettings, BaseInternalExportFileConnectorConfig), passed to OpenCTIConnectorHelper via to_helper_config().
• Set connector-specific defaults (id, name: ExportFileTxt, scope: ["text/plain"]) so the connector is deployable from the manager without mandatory name/scope input.
• Set manager_supported: true in __metadata__/connector_manifest.json and regenerate connector_config_schema.json / CONNECTOR_CONFIG_DOC.md.
• Drop entrypoint.sh in favour of a direct CMD in Dockerfile and Dockerfile_fips; normalize docker-compose.yml and config.yml.sample (removed the obsolete confidence_level and the hardcoded connector.type).

The file structure, class names and processing logic are intentionally unchanged — this is a structure-preserving (lite) migration.

Checklist

• I consider the submitted work as finished
• I have signed my commits using GPG key.
• I tested the code for its functionality using different use cases
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality

Further comments

CONNECTOR_NAME and CONNECTOR_SCOPE move from required to defaulted in the config schema. This is not breaking for existing deployments — explicitly set values still override the defaults — but it does change the generated schema consumed by the platform.

Removing entrypoint.sh changes how the image starts. Any deployment overriding the entrypoint will need adjusting; the standard docker-compose.yml is unaffected.

Pull request overview

This PR migrates the internal-export-file/export-file-txt connector to the connectors catalog / manager-supported configuration model by switching to connectors-sdk Pydantic settings and updating container/metadata artifacts accordingly, while keeping the connector’s processing logic intact.

Changes:

• Replaced legacy config.yml/os.environ loading with connectors-sdk-based ConnectorSettings, passed to OpenCTIConnectorHelper via to_helper_config().
• Marked the connector as manager-supported and regenerated catalog metadata artifacts (schema + config doc).
• Simplified container startup by removing entrypoint.sh and using CMD in Dockerfile/Dockerfile_fips; normalized sample configs and compose env vars.

• scope is described as what the connector is "importing", but this is an internal export connector. This description is surfaced in the generated schema/docs, so it should match the connector behavior.

    scope: ListFromString = Field(
        default=["text/plain"],
        description="The scope or type of data the connector is importing, either a MIME type or Stix Object (for information only).",
    )
