Optimize stock availability query and fix configuration issues

[Kushalnahata17]

Summary

This PR optimizes the stock availability lookup query and fixes configuration issues in the project setup files.

Key Changes

Stock Availability Query Optimization (pos_next/api/items.py)

• Replaced ORM with direct SQL query: Changed from frappe.get_all() to frappe.db.sql() for improved performance when querying stock levels across multiple warehouses
• Added empty warehouse list check: Added early return when no warehouses are found to avoid unnecessary database queries
• Improved null handling: Enhanced the return statement to safely handle cases where actual_qty might be null
• Added missing import: Imported flt utility function from frappe.utils
• Removed commented code: Cleaned up the old implementation that was left as a comment

Configuration Fixes

• Fixed pyproject.toml description: Corrected malformed quote character in the project description string
• Added Frappe dependencies: Added explicit version constraints for frappe (>=15.0.0,<17.0.0) and erpnext (>=15.0.0,<17.0.0) in the build configuration
• Added lodash resolution: Added package resolution for lodash to version 4.17.21 in POS/package.json to address potential security or compatibility concerns

Implementation Details

The stock availability query now uses raw SQL with parameterized queries for better performance when dealing with group warehouses that may have many child warehouses. The query aggregates stock quantities at the database level rather than in application code, reducing memory overhead and improving response times.

Code Review — CLOSE (All changes already on develop)

All three changes in this PR are already present on develop:

1. pos_next/api/items.py — The variant_of field addition to ITEM_RESULT_FIELDS and the frappe.qb stock query refactor were merged in prior work. The file on develop is identical to this PR's version.

2. pyproject.toml — The malformed quote fix and [tool.bench.frappe-dependencies] section are already on develop.

3. POS/package.json — The lodash resolution is already present on develop.

Diffing this PR's HEAD against develop produces zero differences across all three files. The PR's merge state is UNSTABLE because there's nothing left to merge.

Recommend closing as superseded.
