* all: Fix compilation for alloy 2.0.0 upgrade

- Add AnyTransactionRequest newtype for split TransactionBuilder traits
- Bump alloy-rpc-types to 2.0.0
- Add block_timestamp field to Transaction struct literals
- Add Amsterdam hardfork header fields (block_access_list_hash, slot_number)
- Remove .with_recommended_fillers() (now handled by .network())

* all: Install rustls aws_lc_rs as default crypto provider

With alloy 2.0.0 pulling in rustls with aws_lc_rs and object_store
(via reqwest) pulling in rustls with ring, rustls 0.23 refuses to
auto-pick and panics on first TLS use. Install aws_lc_rs explicitly
at each binary/test-harness entry point via a shared helper.

* graph: Add serde(transparent) to AnyTransactionRequest

Without this, serde wraps the inner WithOtherFields<TransactionRequest>
in an extra struct layer when serializing, which would produce malformed
JSON for eth_call RPC requests.
