fix: self-anchoring never stored inclusion proofs, causing concluder failures

[m0ar]

The self-anchoring process didn't store the inclusion proofs in the DB, causing pipeline errors for self-anchored events. This is now implemented so the node immediately can validate the events that it created and anchored.

Approach:

1. anchor-service/src/transaction_manager.rs: Added ChainInclusionData struct and chain_inclusion field to RootTimeEvent
2. anchor-service/src/lib.rs: Exported ChainInclusionData
3. anchor-service/src/anchor.rs: Added chain_inclusion field to TimeEventBatch and TimeEventInsertable, updated conversion methods
4. anchor-service/src/anchor_batch.rs: Flows chain_inclusion from RootTimeEvent to TimeEventBatch
5. anchor-evm/src/evm_transaction_manager.rs:
   • Added AnchorResult struct (moved outside impl block)
   • Modified submit_and_wait to return block hash, timestamp, and tx_input
   • Creates ChainInclusionData in anchor_root with all needed fields
6. anchor-service/src/cas_mock.rs and anchor-remote/src/cas_remote.rs: Added chain_inclusion: None to RootTimeEvent
7. event-svc/src/store/sql/entities/chain_proof.rs: Added From<ChainInclusionData> impl for ChainProof
8. event-svc/src/event/store.rs: Updated ceramic_anchor_service::Store::insert_many to extract and persist chain inclusion proofs
9. Test files: Updated all expectation files to include chain_inclusion: None
