[frontend] - Season selector in leaderboard does not fetch season-specific data

[Hydrax117]

Description

SeasonSelector.tsx renders a dropdown of seasons, but changing the season does not refetch the leaderboard data. The displayed rankings always reflect the current season regardless of the selection.

Acceptance Criteria

• Selecting a season passes the seasonId parameter to useLeaderboard.
• The hook appends ?season=<id> to the API request.
• A loading state is shown while the season-specific data loads.
• The URL updates to reflect the selected season (e.g., ?season=2026-s1).
