Clearer milestones on a Soul's Journey

Every milestone has a matching icon in one consistent style, all tiles are the same size and wrap neatly on a phone, and locked milestones show a lock with their name.

Improvements

• Milestones on a Soul's Journey use matching icons in one style instead of mixed emoji.
• Milestone tiles are all the same size and wrap neatly on a phone.
• Locked milestones show a lock and their name instead of a question mark and ???.

Limitations

• Milestones are unchanged: only how they look is new, and a locked milestone still unlocks the same way.
