8f09efda8f test: expand CDC replication test coverage across features and chaos scenarios (#49043)
## Summary

Extends the CDC (replication) e2e test suite with comprehensive
cross-feature coverage and switchover/failover scenarios on top of
#45624.

## What's Added

### New test files (\`tests/python_client/cdc/testcases/\`)
- \`test_fts_and_text.py\` — BM25 search, text_match, phrase_match,
hybrid FTS+dense, FTS after switchover (5 tests × 2 analyzers)
- \`test_schema_features.py\` — dynamic schema, nullable, defaults,
partition key, clustering key, combined features (7 tests)
- \`test_collection_properties.py\` — TTL, mmap, autocompaction,
multi-property, drop property (5 tests)
- \`test_resource_group.py\` — create, drop, update, transfer replica (4
tests)
- \`test_multi_database.py\` — cross-DB collections, drop DB with
collections, cross-DB operations (3 tests)
- \`test_search_verification.py\` — 6 tests × 7 vector types (search
result consistency, query data sampling, hybrid search, iterators,
filtered search)
- \`test_switchover.py\` — basic, during-writes, all-types, loaded,
indexed, rapid stress, failover (7 tests)

### Shared utilities
- \`base.py\`: +7 schema factories, +4 data generators, +4 verification
helpers, +2 constants
- \`conftest.py\`: +\`switchover_helper\` fixture,
+\`--is-check\`/\`--milvus-ns\` options

## Test plan
- [ ] Run \`pytest tests/python_client/cdc/testcases/\` against
two-cluster CDC deployment
- [ ] Verify each test file runs independently via \`pytest
testcases/test_<name>.py\`
- [ ] Companion PR in zilliztech/test-jobs adds Jenkins pipelines to run
these
