fix: correct pyproject package metadata

[aakvatech]

Summary

Fix pyproject.toml so the project metadata matches the actual Frappe app package.

Changes

• change project name from construction_ms to consms
• align author metadata with the existing package/setup metadata
• replace the blank description with Construction Management Solution for ERPNext and Frappe
• retain Bench-managed Frappe dependency handling and existing Ruff configuration

Why

The Python package and Frappe app are named consms (consms/__init__.py, consms/hooks.py, and legacy setup.py), while pyproject.toml declared construction_ms. With Flit as the build backend, the project/package metadata should match the importable top-level package unless an explicit module mapping is configured.

This change keeps packaging consistent without changing runtime application logic.
