[PR] [fix][broker] Fix delayed-delivery index data loss when trimming overlapping buckets [pulsar]

["void-ptr974 (via GitHub)" <gi...@apache.org>]

void-ptr974 opened a new pull request, #26240:
URL: https://github.com/apache/pulsar/pull/26240

   ### Motivation
   
   When bucket trimming selects an immutable bucket that overlaps the first active ledger, RangeMap returns a clipped range key. The delete path still deletes the complete bucket snapshot, so the delayed-delivery index cannot be recovered after a broker restart.
   
   ### Modifications
   
   - Select only buckets whose complete immutable range ends before the first active ledger.
   - Add a regression test for a bucket that overlaps the first active ledger.
   
   ### Verifying this change
   
   - [ ] Make sure that the change passes the CI checks.
   
   This change added tests and can be verified as follows:
   
   - Ran the bucket trimming tests covering complete deletion, delete failure, no orphaned buckets, and overlapping buckets.
   - Ran pulsar-broker checkstyleMain and checkstyleTest.
