Improve performance oprimizing queries (#56)

* Extend test coverage

* Implement query optimization

* More aggressing code reuse

* Add more indexes and optimize usage

* Fix tests

* Further optimizations, improve counting to rely on backend DB

* chore: add Makefile for frontend asset minification

- Add comprehensive Makefile with targets for JS and CSS minification
- Implements instructions from ram/portal/static/js/src/README.md
- Provides targets: install, minify, minify-js, minify-css, clean, watch
- Fix main.min.js to only include theme_selector.js and tabs_selector.js
- Remove validators.js from minified output per README instructions

* Add a Makefile to compile JS and CSS

* docs: add blank line whitespace rule to AGENTS.md

Specify that blank lines must not contain any whitespace (spaces or tabs) to maintain code cleanliness and PEP 8 compliance

* Update for 0.20 release with optimizations

* Improve Makefile
