I affirm:

• I understand that if I do not agree to the following points by completing the checkboxes my PR will be ignored.
• I understand I should leave resolving conversations to the LandSandBoat team so that reviewers won't miss what was said.

What does this pull request do?

• Guild Point Shop - Disables post-toau items (Signboards, Rings, Emblems, "Way of" key items) by setting their rank requirement to 99. We also set Aurora and Twilight Crystals costs back to 500 GP.
• Base script change - Exposes the guild shop tables to xi.crafting so modules can modify them without touching core scripts.
  • This was moved to [lua] Expose guild point tables to xi.crafting namespace LandSandBoat/server#9082 but required for this pull request. We will need to sync with latest LSB before merging this PR.

Note: DAT Modifications will be required to update the guild shop dialog to reflect crystal prices in menu and items. They are blocked already, but need DAT to make it look nice and accurate.

Steps to test these changes

• Attempted to buy a disabled item and verify it doesn't take Guild Points
• Bought crystals to make sure price was modified back to 500 after reduction to 200
