What is the issue

DSP-25176

Encrypted primary index files are written in a way that hides encryption metadata in holes in the file. Non-trie data like primary keys may span over these holes, which is handled correctly when we read these keys.
However, when we skip a key instead of reading it, we may end up in the wrong position if the key is longer than the metadata.

What does this PR fix and why was it fixed

Implements skip position correction for encrypted primary index files.
Also corrects problems listing partitions when the boundaries of an sstable have been reduced due to zero-copy streaming metadata.
Adds tests for both problems.
Disables early opening for online scrub, which is unsafe because data may transiently disappear.
Makes sure that failed attempts to open a compaction result early are logged but do not stop the operation, by rolling back the prepared transaction checkpoint on error.
Fixes incorrect row index length in openFinalEarly.
Fixes incorrect DecoratedKey minimization.

@blambov This code looks very familiar to the DSE side one. The only CI failure Butler reports it's a timeout.

I only have one q: Does the last commit lack a test maybe?

[blambov]

Test added.
