test: add unit tests for handler and store packages

Browse Source 
- Added TestSearchRequests for store package (0% → 100% coverage)
- Added TestOpenInMemory for store package Open function
- Added TestNewSQLiteRepoNilDB for error handling
- Added TestV1ReplayRequest for handler package (0% → 100% coverage)
- Added TestPrettyJSON and TestFormatTime for inspect helpers
- Added TestJoinPath for path joining utility
- Added TestHandleMockReturnsErrorOnInvalidJSON
- Added TestInspectReturnsHTMLErrorOnRepoFailure
- Added TestCaptureMissingEndpointID, TestV1CaptureRequestMissingEndpoint, TestV1ListRequestsMissingEndpoint

Coverage improvements:
- Handler: 77.1% → 82.2%
- Store: 61.1% → 82.2%
