test: add unit tests for timestamp PDF feature
Add 31 tests across 3 test files covering: - TSA preset configuration (uniqueness, valid URLs, known providers) - Timestamp PDF page logic (file validation, output naming, UI state, drop zone) - TimestampNode workflow node (category, icon, description, presets)
