fix: correct PLAYER_REST_STATE_EXPERIENCE wire indices for all expansions

The REST_STATE_EXPERIENCE field was erroneously set to the same index as
PLAYER_SKILL_INFO_START in all four expansion JSON files, causing the
rested XP tracker to read the first skill slot ID as the rested XP value.

Correct indices derived from layout: EXPLORED_ZONES_START + 128 zone
fields (or 64 for Classic) immediately precede PLAYER_FIELD_COINAGE, with
REST_STATE_EXPERIENCE in the one slot between them.

- WotLK: 636 → 1169  (1041 + 128 = 1169, before COINAGE=1170)
- Classic: 718 → 1175 (1111 + 64 = 1175, before COINAGE=1176)
- TBC: 928 → 1440    (1312 + 128 = 1440, before COINAGE=1441)
- Turtle: 718 → 1175 (same as Classic layout)
