lint: disable leveldb subtree check
This is no-longer a proper subtree, because of direct cherry-picks.

coins: test chainstate flush baseline
Add `CDBWrapper::GetProperty()` and expose it through `CCoinsViewDB::GetDBProperty()` so coins tests can inspect LevelDB runtime properties through the coins view. Use it in a coins DB flush baseline that records the LevelDB layout after flushing while keeping readback coverage for the flushed coin and best block.

validation: randomly compact chainstate
Full chainstate flushes are convenient maintenance points for long-term LevelDB cleanup because the chainstate was just written. Randomize the trigger so nodes that flush near the same height do not compact together. Add blocking chainstate compaction through `CCoinsViewDB::CompactFull()` and give each post-IBD full flush on the normal chainstate a 1/320 chance to start compaction. With hourly flushes this averages roughly every two weeks and makes a six-month miss about one in a million. This keeps the schedule stateless and leaves last-compaction height or timestamp bookkeeping out of chainstate metadata.

coins: compact chainstate in background
Full chainstate compaction can take minutes on large databases. Move `CCoinsViewDB::CompactFull()` to a named `utxocompact` one-shot background thread so validation only schedules the work. When validation selects compaction after a full flush, the chainstate was just written and another write is less likely to be needed immediately. The coins view destructor waits for completion, and a mutex prevents compaction from using `m_db` while `ResizeCache()` replaces it.
