Technical summary

Reflex websocket state code cannot reliably access request headers through router data.

Initialize mutable RouterData/PageData header fields and expose them through get_headers for websocket state handlers.

The relevant code path includes RouterData, PageData, and _init_mutable_fields, so the fix should preserve per-request mutable header storage.

The snippet uses native project logic; headers from Reflex router data are copied before the backend request is forwarded. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import reflex; print('smoke test OK')"
