fix(integration): mount missing SQL files 10-12 in ClickHouse init

3 SQL files were missing from the docker-compose.yml volume mounts:
- 10_perf_indexes.sql (performance indexes)
- 11_views.sql (dashboard views)
- 12_thesis_features.sql (thesis §5 MVs and views)

Also make 10_perf_indexes.sql non-fatal in init script since ALTER TABLE
ADD INDEX may fail if index already exists.
