feat: Add inventory, companion and profession pages

Need to implement equip/unequip skills
Need to take the character's body snapshot
Need to implement magical items to inventory (center section doesn't work yet)
Need to check if the profession's wearable is owned by the character to hide/show wearable gem and colorize or not the picture.

Minor issue: When open skill page and selected wearable is undefined, preview is a white square. Maybe only in foundation.
