Expand gtest coverage across recently changed modules

Adds ~60 new unit tests covering the modules touched in recent bug-fix passes and UI refactors: - RenderTicket: result/finish-count semantics, empty watcher defaults, ticket-reuse rejection - Preferences tabs: behavior options migrated into General/Audio tabs, translation context helper, audio-tab initialization - NodeView: context management, 'Show in Parameter Editor' action wiring - PreviewAutoCacher: construction, pause toggles, single-frame render cancellation, force-cache range - SeekableWidget/TimeBasedWidget: scroll, marker editing, context reset - OCIOLutNode: empty/missing/unsupported LUT paths, string direction values, file-switching regression coverage - ProxyManager: working filename, disabled state, empty proxy fields - Frame/VideoParams/AudioParams/Timecode/ExportFormat/ExportCodec: additional edge-case and enumeration coverage Also fixes the PreferencesAudioTab test crash by initializing AudioManager in the offscreen test environment. All tests pass: ctest --output-on-failure
