Bots Don't Autoequip Tools & Other Misc Weapons (#2346)

<!--
Thank you for contributing to mod-playerbots, please make sure that
you...
1. Submit your PR to the test-staging branch, not master.
2. Read the guidelines below before submitting.
3. Don't delete parts of this template.

DESIGN PHILOSOPHY: We prioritize STABILITY, PERFORMANCE, AND
PREDICTABILITY over behavioral realism.

Every action and decision executes PER BOT AND PER TRIGGER. Small
increases in logic complexity scale
poorly across thousands of bots and negatively affect all. We prioritize
a stable system over a smarter
one. Bots don't need to behave perfectly; believable behavior is the
goal, not human simulation.
Default behavior must be cheap in processing; expensive behavior must be
opt-in.

Before submitting, make sure your changes aligns with these principles.

## Pull Request Description
<!-- Describe what this change does and why it is needed -->
Solve the rest of #2344

Now, bots won't autoequip any weapon from ITEM_SUBCLASS_WEAPON_MISC,
which includes all of the basic tools and some other crap that they have
no need to autoequip, either. Bots are still eligible to equip those
weapons (such as through the "e" command).

Note that MISC includes the Argent Tournament lances. I've not played
WotLK, but I assume those might be relevant for a strategy. It shouldn't
be a problem though because I've intentionally not made bots ineligible
for MISC weapons; they just won't consider them upgrades on their own.

I also cleaned up ItemUsageValue::QueryItemUsageForEquip to consolidate
checks and so on. None of that should be functional, or I screwed up.
The check for MISC is on lines 219 through 221.

## Feature Evaluation
<!--
If your PR is very minimal (comment typo, wrong ID reference, etc), and
it is very obvious it will not have
any impact on performance, you may skip these question. If necessary, a
maintainer may ask you for them later.
-->

<!-- Please answer the following: -->
- Describe the **minimum logic** required to achieve the intended
behavior.
- Describe the **processing cost** when this logic executes across many
bots.



## How to Test the Changes
<!--
- Step-by-step instructions to test the change.
- Any required setup (e.g. multiple players, number of bots, specific
configuration).
- Expected behavior and how to verify it.
-->
Activate selfbot. Unequip all weapons and have nothing in the inventory
except for a MISC weapon such as a skinning knife. Whisper self "equip
upgrade"--nothing should happen. Whisper self "e [LINK TO WEAPON]"--the
bot should equip the weapon.


## Impact Assessment
<!-- As a generic test, before and after measure of pmon (playerbot pmon
tick) can help you here. -->
- Does this change increase per-bot/per-tick processing or risk scaling
poorly with thousands of bots?
    - - [ ] No, not at all
    - - [x] Minimal impact (**explain below**)
    - - [ ] Moderate impact (**explain below**)

There's an extra check but totally meaningless with respect to
performance.

- Does this change modify default bot behavior?
    - - [ ] No
    - - [x] Yes (**explain why**)

They won't auto-equip crap that will prevent them from using abilities.

- Does this change add new decision branches or increase maintenance
complexity?
    - - [x] No
    - - [ ] Yes (**explain below**)



## AI Assistance
<!--
AI assistance is allowed, but all submitted code must be fully
understood, reviewed, and owned by the contributor.
We expect contributors to be honest about what they do and do not
understand.
-->
Was AI assistance used while working on this change?
- - [ ] No
- - [x] Yes (**explain below**)
<!--
If yes, please specify:
- Purpose of usage (e.g. brainstorming, refactoring, documentation, code
generation).
- Which parts of the change were influenced or generated, and whether it
was thoroughly reviewed.
-->

I had GPT-5.4 evaluate different spots where I thought an exclusion
could be added before settling on this one.

<!--
TRANSLATIONS:
Anything new that the bots say in chat must be in a translatable format.
This is done using GetBotTextOrDefault,
which you can search for in the codebase to find examples. Your code
needs to have English as the default fallback,
while the full translations need to be in an SQL update file. The
languages in the file are the nine language
options supported by AzerothCore: English, Korean, French, German,
Chinese, Taiwanese, Spanish, Spanish Mexico, and
Russian. See
data/sql/playerbots/updates/2025_12_27_ai_playerbot_fishing_text.sql as
an example of a translation SQL
update, whose content are called within the codebase at
src/strategy/actions/FishingAction.cpp
-->

## Final Checklist

- - [x] Stability is not compromised.
- - [x] Performance impact is understood, tested, and acceptable.
- - [x] Added logic complexity is justified and explained.
- - [x] Any new bot dialogue lines are translated.
- - [x] Documentation updated if needed (Conf comments, WiKi commands).
