feat(multi_call_entrypoint): demote to non-protocol contract

Mirrors the auth_registry demotion (PR #23106):

- Moves the noir contract from contracts/protocol/ to contracts/canonical/.
- Removes MULTI_CALL_ENTRYPOINT_ADDRESS from constants.nr / aztec_constants.hpp / constants_gen.pil and drops the entry from protocol_contracts.json so the contract is no longer treated as a protocol contract.
- Adds a multi-call-entrypoint stamp sub-package under @aztec/canonical-contracts with TS-only address.gen.ts + freshness test (no Noir consumers of the address exist, so no Noir lib stamp is generated).
- Migrates consumers from ProtocolContractAddress.MultiCallEntrypoint / @aztec/protocol-contracts/multi-call-entrypoint to MULTI_CALL_ENTRYPOINT_ADDRESS and @aztec/canonical-contracts/multi-call-entrypoint: DefaultMultiCallEntrypoint, AztecNodeService.getProtocolContractAddresses, and the embedded wallet bundle/lazy providers.
- Drops the multi-call-entrypoint subdir from @aztec/protocol-contracts and the corresponding aztec.js re-export.
