🐛 [Bug]: Merge PRs #31 and #32 together: check and resolve merge conflicts, documentation & code coverage issues

[syed-reza98]

Description

Merge 2 PR to avoid future code breakdowns

Steps to Reproduce

1. Review all committed files and documentation in PR perf: Optimize analytics queries, component re-renders, and Intl formatter creation across entire codebase #31 and PR Refactor: Eliminate 179 lines of duplicated utility code #32
2. Attempt to merge both PRs into a single PR targeting 001-multi-tenant-ecommerce
3. Identify any merge conflicts between all files and modules (especially utility and formatting modules)
4. Document exact conflict source(s)
5. Resolve conflicts logically and update affected code/documentation
6. Validate all lint, type, and test checks pass
7. Ensure code coverage and functional documentation are updated
8. Complete merge on target branch.

Expected Behavior

All files and documentation are merged from PR #31 and #32, any conflicts are clearly documented and resolved, code coverage is correct, and all tests/lint/type checks pass. Documentation like RATE_LIMITING.md and REFACTORING_SUMMARY.md updated. The merged PR is successfully committed to 001-multi-tenant-ecommerce with no regressions or duplication.

Actual Behavior

Currently, both PRs exist separately, increasing chance of code merge conflicts (especially in utility modules), inconsistent documentation, and possible duplicated changes. A unified merge is needed to prevent fragmented changes and documentation.
