🛠️ Fix database initialization and custom BigInt type handling

Summary

This PR fixes multiple bugs and unsafe behaviors in the database initialization layer and the custom RealBigInt Sequelize data type. It improves runtime stability, correctness of Sequelize usage, and cross-dialect compatibility (Postgres + SQLite).

---

🚨 Fixes

Database initialization (initStorage)

• Fixed incorrect Sequelize typing (AbstractDialect misuse removed)

• Corrected dialect typing to use Sequelize-supported Dialect

• Fixed unsafe port parsing (string → number)

• Improved environment handling for DB host detection

• Added proper error handling for:

  • authenticate()
  • sync()

• Fixed unsafe model association binding order (now guarded)

• Improved logging for DB lifecycle failures

---

BigInt DataType (RealBigInt)

• Fixed incorrect instanceof BigInt usage (replaced with typeof === "bigint")

• Fixed invalid Sequelize ValidationErrorItem usage

• Added proper null/undefined handling in escape()

• Fixed SQL escaping to prevent malformed queries

• Improved sanitize() to safely convert:

  • string → bigint
  • number → bigint
  • boolean → bigint (explicit conversion)

• Fixed unsafe error message construction

• Hardened dialect support detection with optional chaining

• Improved fallback behavior for non-native BigInt dialects (SQLite)

---

🧠 Behavioral Improvements

• Safer cross-database compatibility (Postgres + SQLite)
• More predictable BigInt serialization format (123n fallback encoding)
• Prevents runtime crashes from invalid DB values
• Improves logging clarity for slow queries and DB errors

---

⚠️ Breaking Changes

None (fully backward compatible at runtime)

---

✅ Testing Checklist

• App boots with Postgres
• App boots with SQLite (in-memory)
• BigInt fields store and retrieve correctly
• No validation crashes on invalid DB values
• Associations correctly load on startup

---

📌 Notes

This refactor aligns Sequelize usage with supported APIs and removes unsafe assumptions about BigInt handling across dialects.
