Address review on PgSQL error classifier (PR #5514 )

- Fix: 57014 (query_canceled) is now classified as REPORT_TO_CLIENT
  instead of FATAL (it's a normal cancellation, not a server crash)
- Fix docstring: crash_shutdown is 57P02 (class 57), not class 58;
  class 58 is system/I/O errors
- Add test for 57014 exception (+1 test, plan 25→26)

Extract PgSQL error classification logic (Phase 3.10, #5498 )

New: include/PgSQLErrorClassifier.h, lib/PgSQLErrorClassifier.cpp

Functions:
- classify_pgsql_error(): classifies by SQLSTATE class — connection
  (08), transaction rollback (40), resources (53) = retryable;
  operator intervention (57), system error (58) = fatal; all others
  (syntax 42, constraints 23, data 22) = report to client
- pgsql_can_retry_error(): checks retry conditions (retries left,
  not in transaction — PgSQL transactions are atomic)
