threads the `user_id` parameter through from `run_generation_inner`,
consistent with every other mutation in db/sources.rs.

Add nullable rss_url (TEXT) and rss_discovered_at (TIMESTAMPTZ) columns
to the sources table for RSS feed URL caching. Update the Source struct,

Date parser now supports: 25/03/2026, 25-03-2026, March 25 2026,
25 mars 2026, 15 février 2026, and short month variants.
Articles without dates are no longer routed to a separate category —
they stay in their LLM-classified category with date shown as empty.
This prevents losing good articles in a catch-all section.
