Phase 1a: shared schemas, service layer, server tooling

- shared/schemas/: move Zod schemas out of routes so client + server share them
- shared/types.ts: inferred types and enums for cross-package use
- server tsconfig rootDir raised to ".." so shared/ compiles in-tree
- server/src/services/: ticket, comment, cti, user, auth, notification (stub), search (stub)
- Routes thinned to validate-delegate-return; business logic now testable in isolation
- server/src/lib/httpError.ts: typed HttpError replaces ad-hoc throw shapes
- server/src/lib/logger.ts: pino structured logging replaces console.log
- autoClose job delegates to ticketService.closeStale()
- express-rate-limit on /api/auth/login (10 / 15min / IP)
- vitest + vitest-mock-extended; 20 service-level tests cover auth, ticket, comment, user flows
- CI: lint + test jobs before docker builds
