test(audience-sdk): introduce TestDefaults.PublishableKey

Names the sandbox-shaped publishable-key fixture so the same string
doesn't have to live in 28 separate test files.

- TestDefaults.cs: new internal helper with PublishableKey ("pk_imapik-test-key1") plus the FlushIntervalSeconds and FlushSize defaults shared across the test fixture.
- HttpTransportTests, ImmutableAudienceTests, ConsentSyncTests, DeleteDataTests, SessionTests: 28 inline copies of the publishable-key string read from TestDefaults.PublishableKey.
