UI/UX: Improve visual clarity and consistency

- Align status bars with label padding (HP, Stamina, XP)
- Add clear combat turn indicators (YOUR TURN / ENEMY TURN)
- Display HP/Stamina bars in inventory menu and usage
- Add consistent separators between sections
- Improve feedback for item usage with visible stat changes

Files modified:
- bot/utils.py: Added label_width parameter to format_stat_bar()
- bot/combat.py: Turn headers and separators
- bot/inventory_handlers.py: HP/Stamina display
- bot/action_handlers.py: Separator placement fix

See docs/development/UI_UX_IMPROVEMENTS.md for details
