pkg/aflow/backend/gemini: support explicit credentials config

Update gemini.Config to support passing a *genai.ClientConfig directly in the
configuration struct. This allows callers to explicitly choose the backend
provider and supply the credentials without relying on environment variables
queried inside pkg/aflow.

Additionally, update syz-cluster to pass the API key resolved from GCP secrets.

-----------
syz-agent: support config-driven Vertex AI routing

Add "workflow_backends" map and "default_backend" configurations to syz-agent.
This allows routing specific workflows explicitly to a chosen LLM backend (e.g.,
"gemini" or "vertex") and fallback to a default.

Construct and pass the *genai.ClientConfig explicitly to gemini.NewProvider and
remove os.Setenv calls from the config loader.

Dynamically resolve the cloud project ID via gcpsecret.ProjectName() with environment
fallback to GOOGLE_CLOUD_PROJECT, removing the "cloud_project" field from the JSON config.

Additionally, remove the unused "workflows" ACL filtering list and simplify
validation checks to verify configured workflow names directly against registered
workflows.

tools/syz-aflow: support vertex AI provider option

Add support for the "vertex" provider value to the -provider CLI flag. When selected,
verify GOOGLE_CLOUD_PROJECT is set and configure genai.ClientConfig to target Vertex AI
using Application Default Credentials (ADC).

Otherwise, default to the Gemini Developer API, requiring GOOGLE_API_KEY or
GEMINI_API_KEY env variables.
