fix: 修復 partner 偵測時序 bug（AddOn 從未生效）+ IG meta_key 錯配

TMDO_Infocards::register() 舊版在 bootstrap 當下以 class_exists('TMEETIC_*')
偵測 partner，失敗即 early return。但本 AddOn bootstrap 掛在 plugins_loaded:6，
而 2meet-infocards 要到 :20（tmeetic_run）才 require 自身類別——在 :6 當下
TMEETIC_* 一律不存在，偵測必定失敗，兩個註冊 hook 從未被掛上，整個 AddOn
等同未啟用。

三處修法：
1. 偵測從 bootstrap 移進 hook callback 內執行，hook 一律先掛上
2. 偵測改以 TMEETIC_VERSION / TMEETIC_PLUGIN_DIR 常數優先（檔案解析當下即
   define，早於 plugins_loaded），class_exists() 退為後備
3. bootstrap priority 6 → 3；wpdo_register_custom_tables callback prio 設 5，
   讓本 AddOn 較豐富的定義勝過主外掛無 expected_columns 的版本

同時修正 IG token 兩個欄位的 meta_key 錯配（tmeetic_ig_access_token_enc /
tmeetic_ig_token_expiry），以及 registry 索引 config key expected_indexes →
indexes。

實測驗證：
- wpdo_register_fields 掛載 prio 10、wpdo_register_custom_tables prio 5
- 2meet_vendor_profiles 由本 AddOn 註冊（16 欄位 / 1 索引 / doctor_callback）
- 缺 expected_columns 由 26/29 降為 0/46
- wp wpdo doctor 60 OK / 0 FAIL；anti-EAV lint 通過；站台 200/200
