Build key factory deployment event indexing and registry API

[Chucks1093]

Summary

Index KeyDeployed events from the factory contract and expose a registry API for looking up all keys deployed by a creator and validating that a key address was deployed through the official factory.

Scope

• GET /factory/keys?creator= — all keys deployed by creator wallet
• GET /factory/keys/:contractAddress — validates factory origin and returns key summary
• KeyDeployed events indexed with contract address, creator, and timestamp
• is_factory_key flag included on all key API responses
• Registry updated in real time from contract event stream

Acceptance Criteria

• Creator key list returns all factory-deployed keys in deployment order
• Contract address lookup returns correct key summary and factory flag
• KeyDeployed events indexed without duplication
• is_factory_key flag correct on all key responses
• Non-factory keys return is_factory_key: false without error
