[Bug] Active-first sort applies to MCap and Recent — should only be on Trending

[realproject7]

Problem

Active-first sorting is applied to MCap and Recent sort modes, but per the spec (#958) it should only apply to Trending.

Sort	Active-first?	Current	Expected
Trending	Yes	✅ Yes	✅ Yes
MCap	No	❌ Yes	No
Recent	No	❌ Yes	No
TVL	No	?	No

Why

• MCap sort: Users want to see highest market cap stories regardless of active status. An expired story with $10K MCap should rank above an active story with $100 MCap.
• Recent sort: Pure chronological order. Active status is irrelevant.
• TVL sort: Same as MCap — value-based ranking.

Fix

Remove active-first logic from MCap, Recent, and TVL sort functions. Only keep it in the Trending sort.

Check lib/ranking.ts or wherever the sort logic lives:

• getMcapStorylines() — remove active-first sort
• Recent query — remove active-first sort
• TVL query — remove active-first sort (if applied)
• getTrendingStorylines() — keep active-first sort

Files

• lib/ranking.ts or equivalent
• src/app/page.tsx or discover page

Acceptance Criteria

• Trending: active stories first, then completed ✅
• MCap: sorted purely by market cap descending
• Recent: sorted purely by block_timestamp descending
• TVL: sorted purely by TVL descending
