test: add background crawler timing tests

Added tests to verify background crawler behavior:
- Tests that backgroundCrawl returns immediately when minutes <= 0
- Tests that backgroundCrawl executes at the specified interval
- Tests that Run() returns early when port is -1 (testing mode)

These tests verify the general structure and timing of the background
crawler without requiring a full integration test with actual feeds.

Closes NK-pwogze

Created follow-up tickets:
- NK-rhelrq: End-to-end integration test for complete crawl cycle
- NK-0oti10: Documentation for background crawler behavior
