feat(dl-item-tooltip): match in-game tooltip styling

[victorblino]

Updates dl-item-tooltip to more closely match the in-game tooltip layout and visual behavior.

Changes include:

• Reworked tooltip layout, spacing, typography, stat blocks, section ordering, and component item footer styling.
• Preserved section order from API data instead of reshuffling innate/ability content.
• Added inline description icon/text coloring using API class names such as Spirit, SpiritDamage, BulletResist, MeleeDamage, Heal, MoveSpeed, Slow, and related variants.
