Add two-point conversion and special teams touchdown fantasy points support

[mistakia]

The current fantasy points calculation in player-fantasy-points-from-plays-column-definitions.mjs has TODO comments indicating missing support for:

1. Two-point conversion fantasy points - Currently not being calculated for successful two-point conversion attempts
2. Special teams touchdown fantasy points - Missing support for kick return touchdowns and punt return touchdowns

Current Implementation Analysis

The file currently handles:

• Passing scoring (generate_passing_scoring_sql)
• Rushing scoring (generate_rushing_scoring_sql)
• Receiving scoring (generate_receiving_scoring_sql)
• Fumble scoring (generate_fumble_scoring_sql)

Missing Features

Two-Point Conversions

• Need to identify plays where play_type involves two-point conversion attempts
• Add scoring for successful two-point conversions (typically 2 points)
• Consider different player roles (passer, rusher, receiver)

Special Teams Touchdowns

• Kick Return TDs: Player returns kickoff for touchdown
• Punt Return TDs: Player returns punt for touchdown
• These should be worth 6 points in standard scoring

Files to Modify

• libs-server/data-views-column-definitions/player-fantasy-points-from-plays-column-definitions.mjs (lines 77-78 have the TODO comments)

Acceptance Criteria

• [ ] Two-point conversion attempts are identified and scored correctly
• [ ] Kick return touchdowns are identified and scored (6 points)
• [ ] Punt return touchdowns are identified and scored (6 points)
• [ ] All scoring integrates with existing scoring format system
• [ ] Tests verify the new scoring calculations work correctly
