feat(oauth): Add configurable token_refresh_request_type for GET-based OAuth APIs

Summary

Adds a token_refresh_request_type property to OAuthAuthenticator that controls how the token refresh HTTP request is sent. Previously, the authenticator always used POST with a form-encoded body. Some APIs (e.g., Marketo's /identity/oauth/token) require GET with query parameters instead.

Three modes are now supported:

• body_data (default): POST with form-encoded body — existing behavior, fully backward-compatible
• body_json: POST with JSON body
• query_params: GET with query parameters

The change threads through 5 files:

1. abstract_oauth.py — new get_token_refresh_request_type() method + request dispatch logic in _make_handled_request()
2. declarative_component_schema.yaml — new enum property in the OAuthAuthenticator schema
3. declarative_component_schema.py — corresponding Pydantic model field (hand-edited)
4. oauth.py (declarative auth) — dataclass field + getter override
5. model_to_component_factory.py — wires the property when constructing the component

Review & Testing Checklist for Human

• Pydantic model generation: declarative_component_schema.py was hand-edited. Verify whether this file should instead be regenerated from the YAML schema (e.g., via poe assemble or a codegen script). The enum= kwarg passed to Field() may not enforce validation in Pydantic v2 — check that invalid values are actually rejected.
• No input validation on request type: If an invalid string is passed as token_refresh_request_type, it silently falls through to the default body_data (POST form-encoded) branch. Consider whether an explicit error should be raised for unrecognized values.
• No tests included: The three code paths in _make_handled_request() (query_params, body_json, body_data) have no unit test coverage. Recommend adding tests that mock requests.request and verify the correct HTTP method and parameter encoding for each mode.
• Backward compatibility: Verify that existing connectors and manifests that do not set token_refresh_request_type behave identically to before (should default to body_data / POST with form-encoded body).
