[sql] Add missing weapons, equipment, general and usable items

[sruon]

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.
• I have read and understood the Contributing Guide and the Code of Conduct.
• I have tested my code and the things my code has changed since the last commit in the PR and will test after any later commits.

What does this pull request do?

Every item presently missing.
Everything from the DAT with no alterations (flags, jobs, level, slots, charges, damage, delay, activation time etc)

What I can't figure out without captures is missing: no AH category, no NPC sale price, no model ID, no equipment mods/latents. Called out as comments where relevant.
