The CTFE get-entries handler currently returns Cache-Control: public, max-age=86400 even when the response contains fewer entries than requested. This long cache max-age is problematic when start < tree_size < end, because the response would be expected to change after a new entry is added to the log.

To mitigate this problem whilst retaining some caching benefit, this PR implements max-age=60 for get-entries responses that return fewer entries than requested.
