### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: Auto partition creation can race with dynamic partition
retention. After new partitions are added, the response builder reads the table
partition map and partition info without holding the table metadata lock. If a
retention drop removes one of those partitions in the same window, the response
builder can observe a missing partition or partition item and hit a null
pointer while constructing partition and tablet metadata. This change snapshots
the required partition metadata under the table read lock, returns a normal
error when the partition was already dropped before the snapshot, and keeps
tablet location/cache/backend resolution work outside the table lock.
