Fix profile activity feed layout on mobile — text overflow and truncation

[realproject7]

Summary

The profile page activity tab is broken on mobile. Feed rows have text overflow issues causing content to overlap and get clipped.

Current behavior

• Story titles truncate too aggressively (showing "S.", "S..." for story names)
• Trade detail text ("1089000.00 tokens for 2178.00 PLOT") overlaps with the date and tx link
• "PLOT" text gets cut off, merging with the date ("PLOTMar 20")
• The single-row horizontal layout doesn't work on narrow screens

Expected behavior

• Feed rows should stack or wrap gracefully on mobile
• Story title should be readable (not truncated to 1-2 chars)
• Trade amounts and dates should not overlap
• All text should be fully visible without clipping

File

• src/app/profile/[address]/page.tsx — FeedRow component (around line 1080)

Acceptance Criteria

• Activity feed entries are fully readable on mobile viewport
• No text overlap between event details, dates, and tx links
• Story titles show enough text to be identifiable
• Large token amounts don't break the layout
