feat: week 9 exercise

[ArchILLtect]

This pull request introduces a new service class for week 9 challenges and improves testing and database reset logic. The most important changes are the addition of the Week9ChallengeService class and its corresponding tests, as well as refactoring the database reset method for better reliability. Minor test improvements and formatting updates are also included.

New service and test coverage:

• Added Week9ChallengeService class to wrap core challenge retrieval methods, providing a specialized interface for week 9 challenge operations.
• Added Week9ChallengeServiceTest to verify delegation of calls to the underlying ChallengeService.

Database reset improvements:

• Refactored DaoTestBase.resetDatabase() to use H2's TRUNCATE TABLE ... RESTART IDENTITY and temporarily disable referential integrity for reliable test isolation.

Challenge service test enhancements:

• Added new tests to ChallengeServiceTest for findAll and findById, increasing coverage of challenge retrieval logic.

Minor test formatting updates:

• Updated quote formatting in QuoteServiceTest assertions to use standard Unicode quote characters for clarity and consistency. [1] [2] [3]

The test calls svc.getById(42L) twice, which results in two unnecessary DAO calls. Store the result in a variable to avoid redundant method invocations. The comment acknowledges this but the code should be fixed.

Suggested change

	assertTrue(svc.getById(42L).isPresent());
	assertEquals("Two Sum", svc.getById(42L).get().getTitle());
	verify(dao, times(2)).getById(42L); // or call once then store the Optional
	var result = svc.getById(42L);
	assertTrue(result.isPresent());
	assertEquals("Two Sum", result.get().getTitle());
	verify(dao).getById(42L);
