Subject: [PATCH 1/5] feat: introduce typed verification exceptions using
 maatify/exceptions

- Added VerificationException hierarchy
- Introduced application-level exception mapping
- Converted verification failures to typed exceptions
- Updated tests to assert exception behavior
- Domain logic remains unchanged

Subject: [PATCH 4/5] fix(application): harden exception mapping for
 verification flow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replaced fragile string equality checks with safe pattern matching
- Added mapping for Redis rate limit exceptions → VerificationRateLimitException
- Centralized exception mapping logic for generation and validation flows
- Preserved full backward compatibility with existing domain/infrastructure behavior
- No changes to domain contracts or database schema

Compliance:
- No breaking changes
- All existing tests passing
- Mapping now deterministic and resilient

Subject: [PATCH 5/5] fix(application): restore backward compatibility and
 correct mapping regressions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Restored VerificationInvalidCodeException (removed breaking rename)
- Fixed cooldown mapping to match actual domain message ("please wait")
- Restored original mapping for "too many codes" → VerificationRateLimitException
- Kept Redis rate limit mapping improvement
- Corrected tests to reflect real domain messages instead of patched ones

Compliance:
- No breaking changes
- No behavior changes
- Full backward compatibility restored
- All tests aligned with actual domain behavior
