Fixes #10266.

Description of the problem being solved:

Adds a Reflect Item popup for eligible rare rings and amulets, allowing users to preview Reflecting Mist outcomes without manually editing modifier text.

• Shared multiplier slider with current and legacy ranges, plus per-modifier Positive/Negative buttons. Multiplier slider conforms to the global default item affix quality.
• Opt-In Stat Comparison during the reflecting process.
• Creates and saves a new item by default, preserving the original and adding a “Reflected ” name prefix. This behaviour can be adjusted to override the current item instead by unticking "Create new item".
• Modifiers unaffected by reflection display “Cannot be reflected” with an explanatory tooltip.
• Modifier matching of mods that don't just have negative values, but also different wordings.

Works with Catalysts & Experimented Bases.

Fixed an issue where crafted & essence mods weren't correctly scaled by experimented base implicits.

Steps taken to verify a working solution:

• Headless tests cover all eight eligible experimented jewellery bases, every current/legacy multiplier step, catalysts, special inversions, Aspects, and unscalable modifiers.
• Audited 1,396 modifier-source/item-type combinations; additional tests compare all 499 bench/essence combinations against correctly tagged modifiers on experimented bases. Known unsupported parser descriptions are explicitly allowlisted.
• Tested live comparisons, popup rendering, long-modifier wrapping, copy creation, original-item preservation, name persistence, and save/reload. Existing item parsing and ItemTools regression tests passed.
• Manual testing of a few amulets / rings to verify correct behaviour & scaling for edge case mods (e.g. +1 min frenzy on legacy mode on helicals becoming +3 at x2).
