feat(gofile): add configurable link expiration handling

- Adjusts driver addition metadata to accept LinkExpiry and DirectLinkExpiry options for caching and API expiry control (drivers/gofile/meta.go:10).

- Applies the new options when building file links, setting optional local cache expiration (drivers/gofile/driver.go:101) and sending an expireTime to the direct-link API (drivers/gofile/util.go:202).

- Logs Gofile API error payloads and validates the structured error response before returning it (drivers/gofile/util.go:141).

- Adds the required imports and returns the configured model.Link instance (drivers/gofile/driver.go:6).
