feat(shared): open achievement picker from tracker button

[rebelchris]

Summary

• Replace feed header achievement tracker button navigation with inline AchievementPickerModal opening.
• Reuse existing data/hooks in AchievementTrackerButton (achievements, trackedAchievement, trackAchievement) to power modal selection and tracking.
• Keep existing feature flag, loading behavior, and button size/variant logic unchanged.

Key Decisions

• Followed the established modal pattern from AchievementTrackingWidget to minimize risk and keep behavior consistent.
• Simplified handler implementation by removing unnecessary useCallback wrappers in this component.
• Limited scope to packages/shared/src/components/filters/AchievementTrackerButton.tsx only.

Lint fixes applied

• Read the changed file and check CI status
• Fix orphaned code and unused imports
• Commit and push changes

Root cause: The old handleClick was a useCallback with navigation logic. When replacing it with the new modal-opening version, the body of the old callback was accidentally left behind as orphaned code (lines 100-109 in the original), causing syntax errors and unused import warnings.

Changes made in commit bdbdce8:

• Removed orphaned code block (leftover useCallback body with logEvent, push, and webappUrl references)
• Removed unused imports: useLogContext, LogEvent, TargetType
• Removed unused logEvent destructure
