Stage1 refactor world position method names (#2126)

# Pull Request

This change replaces the non‑standard
WorldPosition::getX/getY/getZ/getO/getMapId wrappers with the core
getters (GetPositionX/Y/Z, GetOrientation, GetMapId) and removes the
redundant wrappers.
Goal: align the module with AzerothCore conventions, reduce local
adapters, and improve long‑term maintainability.

## Design Philosophy

This is a structural cleanup only (coordinate access) and does not alter
any AI behavior or decision logic.
It follows the stability/performance-first philosophy and does not add
branches or extra runtime work.

Before submitting: yes, this change aligns with the principles of
stability, performance, and predictability.

Principles:

- **Stability before intelligence**  
  A stable system is always preferred over a smarter one.

- **Performance is a shared resource**  
  Any increase in bot cost affects all players and all bots.

- **Simple logic scales better than smart logic**  
Predictable behavior under load is more valuable than perfect decisions.

- **Complexity must justify itself**  
  If a feature cannot clearly explain its cost, it should not exist.

- **Defaults must be cheap**  
  Expensive behavior must always be optional and clearly communicated.

- **Bots should look reasonable, not perfect**  
  The goal is believable behavior, not human simulation.

Before submitting, confirm that this change aligns with those
principles.

## Feature Evaluation

Please answer the following:

- Minimum logic required: use core getters (GetPositionX/Y/Z, GetMapId,
GetOrientation) wherever coordinates are needed.
- Cheapest implementation: direct call replacement and removal of
redundant wrappers.
- Runtime cost: negligible (same data access, no additional logic).

---

## How to Test the Changes

- No functional testing required (behavior‑neutral refactor).
- Recommended: compile the module and run a normal server startup as
validation.

## Complexity & Impact

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

Does this change increase per-bot or per-tick processing?
- - [x] No
- - [ ] Yes (**describe and justify impact**)

Could this logic scale poorly under load?
- - [x] No
- - [ ] Yes (**explain why**)
---

## Defaults & Configuration

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

If this introduces more advanced or AI-heavy logic:
- - [x] Lightweight mode remains the default
- - [x] More complex behavior is optional and thereby configurable

## AI Assistance

Was AI assistance (e.g. ChatGPT or similar tools) used while working on
this change?
- - [ ] No
- - [x] Yes (**explain below**)

If yes, please specify:

- AI tool or model used: Copilot
- Purpose of usage: Translate this PR text from french to English

## Final Checklist

- - [x] Stability is not compromised
- - [x] Performance impact is understood, tested, and acceptable
- - [x] Added logic complexity is justified and explained
- - [x] Documentation updated if needed

## Notes for Reviewers

This is a core-friendly cleanup only, with no behavioral change.
No additional logic or CPU cost is introduced.
