RFC: Shared types — @guardm/types (path alias, no monorepo)

[Khoa-Dam]

Cross-repo companion to Khoa-Dam/GuardM-fe#8.

See that issue for full details. API-side changes required:

1. Create src/types/ directory — decorator-free types only (interface, type, enum, pure const)
2. Migrate existing enum files to thin re-exports from src/types/:
   • src/enums/crime-type.enum.ts → export { CrimeType } from '@guardm/types'
   • src/enums/verification-level.enum.ts → export { VerificationLevel } from '@guardm/types'
   • src/auth/enums/role.enum.ts → export { Role } from '@guardm/types'
3. Add to tsconfig.json:

   "paths": { "@guardm/types": ["./src/types/index.ts"] }

4. Remove local ParsedReport and AreaAnalysis interfaces from ai.service.ts — import from @guardm/types
5. Remove local CrimeHeatmapData from crime-reports.service.ts — import from @guardm/types

All existing API internal imports (import { CrimeType } from '../../enums/crime-type.enum') continue to work with zero changes.
