fix: make table diffing backwards compatible

[phiSgr]

handle

• old infra map where the key (table ID) does not contain db name
• remote_plan where the remote ID
  • is old (point 1)
  • contains another DB name

---

Note

Make infra map diff/plan compatible with old table IDs (no DB prefix) and cross-DB IDs, add default_database to proto, and add E2E backward-compat tests in CI.

• Core/Infra Map & Planning:
  • Use stable table IDs via Table::id(default_database) across diff/reality checks; add helper find_table_from_infra_map to match legacy IDs without DB prefix.
  • InfrastructureMap.diff_tables(_with_strategy) now keys by IDs and uses target default_database for comparisons; filters adds/removes via new matching.
  • reconcile_with_reality normalizes legacy map keys (rehashes IDs with DB) and updates default_database from project.
  • Add default_database to proto (InfrastructureMap) and round-trip it in serialization.
• Partial Map (DMv2):
  • Clear primary_key flags when engine doesn’t support ORDER BY; propagate table TTL/index settings; compute IDs with DB.
• Reality Checker:
  • Map actual tables by new ID format, compare with map after normalizing DB; compute missing/unmapped/mismatched using ID-aware logic; update tests accordingly.
• ClickHouse:
  • Include database in TableWithUnsupportedType; richer logging for column modify; warn (not debug) on drop+create cases in diff strategy; refine PK/engine/partition handling.
• Tests & CI:
  • Add E2E backward-compatibility tests (backward-compatibility.test.ts) and new GitHub Actions jobs for TS and Python; include them in final status gate.

We should merge but it looks like there is still some things we need to look into for the table diffing
