Rename integration_test_properties to mockmvc_unittest_properties

[duanemay]

The file name integration_test_properties.yml was confusing since it was only used during some unit tests, mostly mockmvc (via @DefaultTestContext) and:

• TestZonifyGroupSchema_V2_4_1 - Database schema/migration test
• UaaBootServerCustomizerTest - Boot server configuration test
• SmtpConfigurationTest - SMTP configuration test (uses nested @DefaultTestContext)
• YamlConfigurationValidationTests - YAML validation test (sets UAA_CONFIG_URL directly)

Pull request overview

Renames the test-only UAA YAML configuration file to better reflect its primary usage by MockMvc-focused unit/component tests (e.g., via @DefaultTestContext), and updates references/documentation accordingly.

Changes:

• Add uaa/src/test/resources/mockmvc_unittest_properties.yml as the new canonical test config YAML.
• Update tests/initializers to point UAA_CONFIG_URL at the renamed YAML.
• Update zone-path feature documentation to reference the new file name.
