eth/filters: fix race in pending tx and new heads subscriptions (#33990)
`TestSubscribePendingTxHashes` hangs indefinitely because pending tx
events are permanently missed due to a race condition in
`NewPendingTransactions` (and `NewHeads`). Both handlers called their
event subscription functions (`SubscribePendingTxs`,
`SubscribeNewHeads`) inside goroutines, so the RPC handler returned the
subscription ID to the client before the filter was installed in the
event loop. When the client then sent a transaction, the event fired but
no filter existed to catch it — the event was silently lost.

- Move `SubscribePendingTxs` and `SubscribeNewHeads` calls out of
goroutines so filters are installed synchronously before the RPC
response is sent, matching the pattern already used by `Logs` and
`TransactionReceipts`
