fix(oracle): Oracle 11g compatibility and sidebar improvements

- Rewrite FETCH FIRST to ROWNUM for Oracle 11g (no 12c+ syntax)
- Filter APEX_*, FLOWS_*, $-prefixed system schemas from sidebar
- Set schema prefix on table nodes for schema-aware databases
- Use all_objects instead of all_tables+all_views (4x faster)
- Disable statement cache to avoid stale cursor issues
- Update rust-oracle with streaming TTC, drain fixes
