fix(sqlserver): align dialect with core API changes and bump CI dependencies

- Change dialect __init__ default version from (16,0,0) to None, call
  super().__init__() first to enforce version adaptation via
  introspect_and_adapt()
- Replace supports_returning_clause() with DML-specific
  supports_returning_insert/update/delete() (all True, OUTPUT clause)
- Fix DEFAULT value escaping: use _escape_sql_string() instead of
  manual inline replace
- Add constraint capability overrides: supports_constraint_enforced()
  (False), supports_fk_match() (False), supports_deferrable_constraint()
  (False)
- Bump CI: activerecord to release/v1.0.0.dev27, testsuite to
  release/v1.0.0.dev14
