Extends the cache service (PR #23) to two new use cases:
- /api/v1/greet/{name} and /api/v1/greet?name=X now cache responses per name (60s TTL)
with X-Cache: HIT/MISS header
- New POST /api/admin/cache/flush endpoint (X-Admin-Password header for auth)
returns 200 with {flushed, items_flushed, timestamp} or 401/503
Companion to PR #22 (rate limit) and PR #23 (cache service).
Changes:
- pkg/server/server.go : handleGreetQuery + handleGreetPath cache layer,
handleAdminCacheFlush handler, /api/admin route registration
Note: replaces the previous greetHandler.RegisterRoutes call with explicit
route handlers to add the cache layer. The greet service itself is unchanged.
Test coverage: deferred to BDD (the existing greet BDD scenarios exercise
the same handlers; cache hit/miss behavior is incidental and easy to verify
via curl + X-Cache header).

compile (used non-existent test helpers).
