Improve streak display logic: show strongest streak (current vs longest)

📈 Improve Streak Logic to Show Strongest Contribution Streak

Problem

Currently, the API only displays the Current Streak.
This creates a poor user experience when a user breaks their streak (e.g. misses one day).

In such cases, the trophy may show 0 or 1, even though the user may have achieved a strong Longest Streak in the past (e.g. 100 days).

🎯 Goal

Ensure the trophy always represents the user's strongest contribution consistency.

💡 Proposed Behavior

• If Current Streak > Longest Streak → show Current Streak
• If Longest Streak > Current Streak → show Longest Streak
• Display only one streak value
• Reuse the existing streak UI (no new sections)

In short:
The streak shown should always be the best streak the user has achieved so far.

⚙️ Implementation Notes

• This is a logic-only change
• No UI or SVG changes required
• The API response must remain backward compatible
• The existing current_streak field should continue to be used

⚠️ Constraints

• Do NOT change the API response structure
• Do NOT add new UI sections
• Do NOT break existing behavior
• The change should feel intuitive by default
