* Fix second-order SQL injection in currency_symbol config

The currency_symbol value was concatenated directly into SQL queries
without proper escaping, allowing SQL injection attacks via the
Summary Discounts report.

Changes:
- Use $this->db->escape() in Summary_discounts::getData() to properly
  escape the currency symbol value before concatenation
- Add htmlspecialchars() validation in Config::postSaveLocale() to
  sanitize the input at storage time
- Add unit tests to verify escaping of malicious inputs

Fixes SQL injection vulnerability described in bug report where
attackers with config permissions could inject arbitrary SQL through
the currency_symbol field.

* Update test to use CIUnitTestCase for consistency

Per code review feedback, updated test to extend CIUnitTestCase
instead of PHPUnit TestCase to maintain consistency with other
tests in the codebase.
