Weapon type filter

[shimotron]

Adds a "Weapon types considered" section to the General page, mirroring
the existing armor-type filter. Unchecked weapon subtypes stop generating
upgrade arrows, tooltip verdicts, loot alerts, and quest-reward marks.
Useful for hiding weapon kinds you can equip but don't want to gear (e.g.
a caster hiding staff/2H arrows).

Built by mirroring the armor-filter pattern across the same touch points
(storage in 01_profiles, a "wrongweapon" gate in 04_score next to
"wrongarmor", accessors in 09_lootalert, checkboxes in RefactorGearUI,
label in 05_tooltip).

Two bugs found and fixed while building it:

1. GetItemInfo returns PLURAL subtype strings ("Bows", "Guns", "Staves"),
   not singular, so a hardcoded list never matched. Now queries the
   client's own subclass list.
2. The weapon item class is not at a fixed index on this client (index 2
   is Armor). Now locates the class by name via GetAuctionItemClasses,
   with a weapon-word safety net so a wrong index can't leak armor names
   onto the page.

Filtering is per character and hide-only. Verified by syntax check and
offline simulation of the addon's own code against the Ascension live
client's subtype/class strings, not in-client, so worth a spot-check
before merging. Credit to a couple of us on the CoA Discord who surfaced
the plural-string bug testing bows and polearms.

Heads-up: the diff looks huge (thousands of lines) due to a line-ending
change on upload, not real edits. The actual change is ~small; the
line-ending noise can be normalized if you'd prefer.
