Add repository selection to chain creation modal

- Update CreateChainModal to include repository input fields
- Add repository suggestions from history using getRepositorySuggestions
- Support both remote (URL) and local (path) repositories
- First repository added becomes primary automatically
- Pass repositories to CreateChainRequest

Also includes backend changes:
- Copy chain repositories to contracts when created from definitions
- Add created_at field to ChainContractDetail
