fix: replace static whatsapp-rust-bridge imports with lazy dynamic loading

The whatsapp-rust-bridge package contains a top-level await on an inline
WASM binary, which propagates through the ESM graph and causes
ERR_REQUIRE_ASYNC_MODULE when CJS consumers try to require() this package.

Replace all static imports from whatsapp-rust-bridge with a lazy-loading
bridge module (wasm-bridge.ts) that uses import().then() instead of
top-level await, keeping the dependency out of the static ESM graph.
