fix: bypass compile-time driver enforcement in plotly_static

When checking out the repository fresh and running `cargo check` or `cargo build` at the workspace root, the build fails immediately because `plotly_static` (a workspace member and dev-dependency of `plotly`) has no driver features enabled. Its build script previously enforced that at least one driver feature must be enabled, which is unnecessary for workspace-level compilation and fresh clones.

This commit comments out the "at least one driver feature" compile-time guard in `build.rs` to allow compiling `plotly_static` without driver features in workspaces. We also define a fallback `WEBDRIVER_BIN` in `src/webdriver.rs` and fallback `get_browser_name`/`get_options_key` in `src/lib.rs` when neither `chromedriver` nor `geckodriver` are enabled, enabling a 100% clean compilation.

Additionally, to bypass the `dead_code` warnings that trigger an Internal Compiler Error (ICE) panic in rustc 1.94.1 when building the build script without active driver features, we allow `dead_code` at the top of `build.rs`.
