v_ahb_diff): make view less general purpose but faster#228Conversation
this change restricts the use of `v_ahb_diff` to compare the SAME prüfidentifikator between 2 format versions where the older version is actually older than the newer. before this change you could also compare in the opposite direction or compare different prüfidentifikators. this is no longer possible. but we get significant performance gains.

Pull request overview
This PR optimizes the v_ahb_diff database view by restricting its usage to compare the same prüfidentifikator across format versions where the older version chronologically precedes the newer version. The optimization trades generality for performance by eliminating unnecessary comparison combinations.
Key Changes:
- Restricted comparisons to matching prüfidentifikators only
- Added constraint that old format version must be less than new format version
- Updated documentation to reflect the new limitations introduced in version 0.32
