test: improve SST progress test with realistic data volume and timing

- Load 2M documents before JOIN to ensure meaningful SST transfer
- Check SST variables immediately after JOIN starts (no delay)
- Use specific regex patterns instead of catch-all patterns
- Simplify test comments for better readability
- Fix manticore-load usage with proper --load parameter

-Test for SST (State Snapshot Transfer) progress monitoring during table replication
-Issue: https://github.com/manticoresoftware/effyis/issues/390
-
-Problem: When adding a large table to cluster via ALTER CLUSTER ADD, there was no way
-to track replication progress. Users couldn't determine how much was copied or remaining.
-
-Solution: Added SST progress variables to SHOW STATUS:
-- cluster_<name>_sst_total: Overall progress (0-100)
-- cluster_<name>_sst_stage: Current stage (e.g., "send files")
-- cluster_<name>_sst_stage_total: Progress of current stage (0-100)
-- cluster_<name>_sst_tables: Total tables being transferred
-- cluster_<name>_sst_table: Current table being transferred (e.g., "3 (products)")
-- cluster_<name>_node_state: Node state (donor/joiner/synced)
-
-This test validates that SST progress variables exist in SHOW STATUS output.
