Depends on #13060 cleanup change. This PR is going to be rebased when it's
merged. Please look at the last commit.

# Summary
Prior to this change, when a cache object was served via the last_open_read
hit path in `CacheVC::handleRead`, it was never promoted to the RAM cache. Only
objects going through `handleReadDone` (disk reads) were eligible for RAM cache
promotion. This meant that frequently-accessed objects could be repeatedly
fetched from disk even when they should have been promoted to RAM cache.
This change adds a RAM cache put call in the last_open_read hit path, using
the same _ram_cache_cutoff_check logic that governs promotion in
handleReadDone. The cutoff check helper was extracted in a prior cleanup commit
to enable this reuse.
# Changes:
- Extract _ram_cache_cutoff_check() as a private method on CacheVC
- In `CacheVC::handleRead`, after a last_open_read RAM hit, call
`stripe->ram_cache->put()` if the object passes the cutoff check, with
`http_copy_hdr` derived from handleReadDone behavior.
