Subject: Update create contract page to use dynamic templates (#29)

* feat: Add contract type templates API endpoint

Add a new API endpoint to provide contract type templates (workflow
definitions) separate from file templates. This enables the create
contract page to dynamically show available contract types.

Changes:
- Add ContractTypeTemplate struct in templates.rs with id, name,
  description, phases, default_phase, and is_builtin fields
- Add built-in contract types: 'simple' (plan/execute) and
  'specification' (research/specify/plan/execute/review)
- Add GET /api/v1/contract-types endpoint returning all contract types
- Add frontend ContractTypeTemplate interface and listContractTypes()
  API function

* feat: Update create contract modal to use dynamic templates

- Add ContractTypeTemplate interface and listContractTypes API function
  to frontend api.ts
- Add GET /api/v1/contract-types backend endpoint that returns built-in
  contract types (simple, specification) with their phases and defaults
- Update create contract modal to fetch contract types dynamically when
  opened, with loading state and fallback to hardcoded types on error
- Dynamically render contract type selection buttons from fetched types
- Update phase dropdown to use phases from selected contract type
- Replace static getValidPhases/getDefaultPhase calls with dynamic data
