Remove the unused cache lifetime setting (closes #69)

CacheConfig.CacheTTL was set to DefaultCacheTTL (24 hours) and never read, so cached images never expired. Remove the field, the constant and the line that set it. Cached source and transformed images stay until eviction removes them to keep the cache within cache_max_bytes. Existing tests lose only the CacheTTL line of their cache config; no test's checks change. Model: opus-5-5
