Retention panel's "currently using" line and usage bar were always blank — totalStorageBytes() existed but was never wired into the settings response, so retention.storageUsedMB was undefined on every load. Now computed fresh on every GET/PATCH /api/admin/settings. Tracked events gain a keywords field: only items whose title/summary/ body contain at least one of them (word, phrase, or emoji — e.g. 🇮🇷 for an "Iran war" event) qualify for that event's recap, instead of every item from its assigned sources. An item from an event-linked source that doesn't match now falls through to normal synthesis rather than being silently dropped. Also added the source-assignment + keyword-filter edit UI to EventsTab.svelte, which had no way to populate sourceIds at all before this (the "assign from the Sources tab" comment referenced a feature that was never built).
