hsiegeln e2f784bf82 fix: deduplicate processor stats using uniq(execution_id) ...

Processor execution counts were inflated by duplicate inserts into the
plain MergeTree processor_executions table (chunk retries, reconnects).
Replace count()/countIf() with uniq(execution_id)/uniqIf() in both
stats_1m_processor and stats_1m_processor_detail MVs so each exchange
is counted once per processor regardless of duplicates.

Tables are dropped and rebuilt from raw data on startup. MV created
after backfill to avoid double-counting.

Also adds stats_1m_processor_detail to the catalog purge list (was
missing).
