Update LPW achievement text based on count

[shippy]

Related to #120

Implements dynamic achievement descriptions based on LPW (Low Point Win) counts in the agg__lpw_count.sql file.

• Introduces a case statement within the achievement_base CTE to assign different achievement descriptions based on the LPW count. This change allows for personalized feedback to users based on their performance in debates.
• For LPW counts of 1-2, sets the achievement description to acknowledge the user has won a few debates despite the odds.
• For LPW counts of 3-5, updates the description to highlight the user's consistent performance in challenging debates.
• For LPW counts of 6 or more, changes the description to celebrate the user's exceptional skill in winning debates against higher-scoring teams.
• Maintains the original structure of the SQL file while integrating the new conditional logic seamlessly into the existing codebase.
