Improvement: Migrated Skill Type Utility Methods into Their Own Class

[IllianiBird]

A few months ago I promised Luana that I would rewrite our SkillType class, converting it into an enum instead of the weird array thing we currently have. This PR is the first step in that direction, moving various utility methods into their own utility class.

The next step will be the enum migration itself. However, as that's liable to be a chunky PR, I wanted to be kind on whoever reviews the PR by moving this initial setup work into its own PR.

As this PR touches on a wide swathe of the codebase I'm expecting copilot to find a bunch of issues. However, unless those issues relate directly to this refactor they will not be addressed. That is to ensure we're not introducing new issues with this change and to retain some degree of change scope.

Pull Request Overview

This PR refactors skill-related utility methods from the SkillType class into a new dedicated SkillUtilities class, replacing experience level constants with new ones prefixed with SKILL_LEVEL_. This is the first step toward converting SkillType from its current array-based implementation to an enum structure.

• Moved utility methods like getExperienceLevelName(), getColoredExperienceLevelName(), and getExperienceLevelColor() to SkillUtilities
• Replaced all EXP_* constants with SKILL_LEVEL_* equivalents throughout the codebase
• Added localization support for skill level names through a new resource bundle
